This was the BEST EXPLANATION OUT OF ALL EXPLANATIONS IVE RECEIVED IN SCHOOL AND ON THE INTERNET. I am very good in math and passed because I know the operations…but never could understand why a negative times a negative is a positive is a positive until now! Thank you
Finally, someone answers the WHY a minus times a minus equals a positive! Everyone else is trying to walk a number line this way or that. THANKS SO MUCH!
For years, I have responded to "Why does negative times negative = positive?" with "it's a debt being cancelled, which is a positive thing for you." To find a video that that so eloquently explains it in concrete concepts with visuals = I love it! I will be showing this video in all my high school courses.
I have a question. We always calculated the -x-=+ in this video as taking away debt but what does it mean for someone who doesn't have debt and only has money. Because sometimes in math there are additions like +4-(-2). In this case for someone who doesn't have debt in the first place and only has money how does -(-2) or -(-a) work here and how does he get richer which means positive? Can you kindly explain?
Im 39 years old and I would avoid using calculations of two negatives because I couldn't understand how to make it work in the real world. After watching this video it makes exact sense as to when to use this type of equation. I went down this rabbit hole because I was learning algebra again and I saw a question that had -1^2 and I assumed the answer was -1 and so I ended up here after a few hours of pondering why two negatives = a positive. Awesome video and I wish they taught this way in shcools tbh.
These are the types of comments that make my day. Thank you for sharing that. And if you have any further questions about anything, then drop me a message at anytime.

@Ramy Melhem Naturally,if i have 6$ before I could payoff my debt and remain zero in savings. 👉I have debt of 6$ my friend paid off it now iam free of debt and I have zero amount with me. It's null zero, How is it positive practically? please explain.
🙏🏾🙏🏾🙏🏾 Thank you, this is the 3rd video I've watched on this topic. I was confused with the number line explanations. The day you've related this to money intuitively makes so much sense to me.
fabulous!!! My grandson didn't want to just learn the rules.. he wanted to understand it. You are the only one I could find that taught it in real world examples. Thank You!!
First time in my life this ever made sense! I asked this in a high school math class and no one could ever really explain it. I love how you use the words to create a logical argument that mirrors the symbolic math functions.
Thanks so much for sharing this, Chris. I love helping people realize this sort of thing and when it brings clarity then I'm happy. If you are still interested in diving deeper into this topic then I encourage you to read upon a 7th century mathematician named Brahamgupta who invented this entire system to keep track of his money.
Thank you so much for explaining! I never used to understand why two negatives multiplied with each other equaled a positive until I came across this video.
This is a master class of patience and complete lack of ego. The ridicule I felt not understanding this stopped me from trying and me avoid maths education. Things could have been different and will be from now on wards. Thank you
Sorry you had to go through that frustration through all those years. Truly special to hear that I was able to help change that in some capacity. Keep fighting the battle and if you have any questions please let me know.
I'm an English teacher in Japan, and have had my students try to explain these equations, and I have to say that this is the best explanation of neg. X neg. = pos. that I have come across. I still have a couple issues with it because I just see it as somehow ultimately reduced to zero. But then again, my friends call me the ultimate reductionist. haha. Anyway, you are an excellent teacher and your students are very lucky.
The best it could be is 0. In his last example - 2 x -3 = + 6 he then reveals the 6 that was in the bank, if you are just seeing the expression ( what he shows is not an equation) how do you know what was in the bank. I want to see it on a number line.
@@simpleman283 -2 x -3 = 6 is an Equation and not an expression. I'm not sure that I understand your main question, but it sounds like you are doubting how there could be $6 in his bank account at the end. Consider it like this, if you started with $6 in your account, then racked up $6 credit card debt, then your bank account is worth zero. If your dad said he will pay off your cc bill then you are back to $6 again.
@@ramymelhem -2 x -3 = 6 is an equation, agreed. I was talking about - 2 x -3. To me it is just a rule we follow to all stay on the same page, like PEMDAS. They could have made the rule from left to right no matter the operation. Anyone can see -3 + -3 + -3 + -3 + -3 = -3 x 5 = -15 or -5 + -5 + -5 = -5 x 3 = -15. In your explanation you told us to ignore the $6 that was in the bank and look at the expression -2 x -3 then pull it down after we got to 0. In order to evaluate an expression we need all the information, there could have been $6 in the bank or $7. To me subtracting groups is not multiplication. If that is truly subtracting groups then we need a new math symbol such as (G). -(2)G(-3). I know you put a lot of thought and effort into your presentation and I am not trying beat you up in any way but it still is not very clear.
@@simpleman283 I'm honestly not sure if you are trolling with your arguments but I will assume that you mean well. First off, I didn't invent this explanation. I am re-explaining it the way the founder of this entire methodology explained it in his book 1500 years ago. Now allow me to attempt to counter argue your statements. 1. -3 + -3 +-3 + -3 + -3 is not -3 x 5 but rather 5 x -3. It won't impact the answer, but it does make a difference in terms of understanding the literal meaning of the expression. We have 5 groups of -3 in 5 x -3. 2. I suggested to ignore the red tiles (+2 x +3) to draw attention to the blue tiles which represented the credit card statement so that we could derive an expression for it. 3. It's absolutely and utterly irrelevant as to whether we started with $6, $7, or $82.32 in the bank account. What matters is that removing a debt increases your net-worth. That is basic financial literacy. 4. It's not up to you or me to decide whether or not "removing groups" is or isn't considered to be multiplication. Multiplication in its essence refers to deriving "repetitive groups" of any asset, debt, abstract, or non-abstract entity. X=groups plain and simple. You can either 'add' groups or you can 'remove' groups and both would be considered 'multiplication'. There is no need to over-complicate it. Why would you need to start a new math symbol 'G' to represent what an 'x' already does perfectly. How would that change Anything? I feel like the gap in your understanding arises entirely from a mathematical literacy perspective. You understand the difference between an Equation and an expression perfectly fine, but you aren't totally clear as to how multiplication expressions and symbols truly function.... and then you aren't completely sure as to what the positive and negative symbols in front of each number represents. I go through that in the first 3-min of the video. And all that is totally ok because we are all here to learn. Let me know if you have any other questions. I'm happy to help. Let me know if you have any other questions.
It makes perfect sense and seems so obvious when it's explained like this! I wonder why so many of us including myself and math teachers couldn't see it until it was demonstrated in this video so thoroughly and eloquently!
I have a question. We always calculated the -x-=+ in this video as taking away debt but what does it mean for someone who doesn't have debt and only has money. Because sometimes in math there are additions like +4-(-2). In this case for someone who doesn't have debt in the first place and only has money how does -(-2) or -(-a) work here and how does he get richer which means positive? Can you kindly explain?
Love this so much!! I’m a teacher and I always try to answer the, “why?” and relate it to real for the kids. I was thinking about negative numbers and couldn’t figure out why it works. Thank you for teaching me so I can possibly teach someone else in the future! Take care.

Best video on UA-cam. A dollar saved is a dollar earned. If I borrow $10 (-10), taking away that negative is +10 for me. Thinking that you have an extra $10 is what confuses people. The $10 that was borrowed was something that I never had, so getting back to zero is a plus 10 for me. Thanks for the vid!!!
Thank you! I’m helping an awesome 23 year old who never had the chance to go to school but is going for his GED. This helps so much to explain something I realized I never fully understood! Great job; way better than any other explanation I’ve seen!
I am compelled to say maths would be demystified and made easy if the world acknowledged that a lot of people who find maths hard are visual learners who do not like cramming maths rules and formulas only but to seek to understand how and why, hence there is a there is a great need to train visual teachers for maths alone as a stand alone speciality of teaching. The Chinese saying that there is no bad student but only a bad teacher is true. You are the best teacher on youtube TBH, please continue to make more math/educational videos.
Wow Precious Dee. I am so honored and humbled at the eloquence of your sentiment. Thank you so much for taking time out of your day to acknowledge my efforts at bringing a more visual aspect to maths education. I've been meaning to revive my channel and you have definitely inspired me to do so in the near future. Thank you.
Excellently explained Ramy Melhem Sir! I am one of those people who just took this - x - = + and didn't ask why. Thank you for making me love math even more.This logic will be with me forever now. Respect to you! :)
Thankyou, like most people i only robotically learned what the symbols meant WITHOUT knowing what they really meant. You have brought to life something important
8 months ago I came hunting the answer to this question. You were very patient with me and helped me, finally get it. I came back to say Thank You again, Merry Christmas Mr. Melhem.
After reading god know's how many articles and watching X number of videos and being none the wiser, it finally makes sense! Thank you so much for posting this video and your simple explanation! It has never been explained to me that the first operator is essentially stating whether to add or subtract something and the second whether the thing being added or subtracted is positive or negative...I always thought of it more literally. In school, we were taught to accept that a negative times a negative is positive, but never why.
I'm happy I was able to make a difference in your understanding of negative multiplication. It's viewers like you who I appreciate. 🙏🙏 Let me know if you have any other questions.
awesome ... this video made my son quickly understood the mystery of negative multiply operation ... believe me it would be the most sad moment for any father in the world when you can"t find the answers of your child, thank you.
Jimmy Lukardy thanks for the feedback Jimmy. I am very happy to have been able to help. Please let me know if u have any topics ud like me to cover in the future.
Excellent video. This is what makes UA-cam cool. I love learning on YT and I love knowing that someone cared enough to explain this to the world. Thank you so much!
bro i am 13 years old and now i have realised that you are the best for explaning maths this is a basic but main question that everybody has and only few of us know thank you for explaning i have seen and asked many videos for this thanks you have got a new subscriber
Thank you so much i am Ramesh from india,iam 50years old i was not undetstood when i was a student in school but thanks from your activity at least i will make my daughter doubts of why negative times negative is positive .
Although I learned this years ago and just accepted it as how things are. The way you showed it, now adds the logic behind it. It really makes a lot of sense taught this way.
Thank you. The video made sense because you showed me the practicality of the math, not just told me a stupid rule to remember. Amazing teacher. You rock!
I have had a learning disability since the second grade. I wanted to get my degree in Hospitality but the Algebra was not taught to understand in high school. I am using my 1 year off to learn Algebra before I take the course. I got stuck on neg x neg = positive. You explained it so well that I now fully understand the concept. You explained WHY it equals a positive. Thank you. Subscribed and shared.
In the ninth grade I took algebra, and in the first week I was lost. What submarined me was this multiplying a negative times negative and producing a positive. It made no sense to me, and I just could not get past it. I was completely lost the entire year. At that time I started telling myself a story that I was bad at math. I'm 65 now and have decided that that was just a story that I told myself and I don't know if I'm any good at math because after that first week in algebra, I avoided it like the plague. So I got into my head to take a look at an introduction to algebra UA-cam video. And guess what happened. Five minutes into the video, once again it was WTF? But this time I decided I was going to get an answer. I've been through a dozen different explanations, and this is the first time that it's actually made sense. If you were here I'd reach out and hug you. This is a brilliant explanation
Virtual hug, Lance. 👐 Thanks for taking the time to share your story with me. That means a lot to me. Im really happy that i was able to shed some light upon this topic. Unfortunately too many students are in the same boat, blindly following the math rules given to them. Thank you again 🙏 If you have any further questions, then please let me know.
I've known since primary school the "rule" for negative x negative and I have watched this and many other videos on this.. but my logic was the answer is the difference between the "starting point" being a negative and how many places it would move in the positive direction. Which would make the new position zero and the difference between that was +6. Is this right? The answer is just the difference between the starting and end point/sum? Rather than literally going from negative nothing to positive something which would mean a movement of +12 which is what I think mixes people? Rewording my clarification, the negative x negative equation is only giving the total movements and not the literal new position or total of "things" or "dollars"..?
wow! i'm old and have trird to find the answer to this since middle school, NO ONE has ever explained it. I feel like life's greatest mystery has been sovled thank you. instantly sub'ing based off of this video.
Ramy, since so many ppl are sharing their age, I’ll just say a couple of things: 1) I’m a week shy of the 4th decade, reasonably well-educated, and I never quite understood the “why” for this problem until today. I figured out part of it out on my own in the morning, but your video rounded out the day in spectacular fashion for me. Thank you. 2). If I may just point out, that re the end of the video, the final result of the positive $6 is NOT the $6 he made from mowing lawns. Rather, it’s the $6 came from the bff (that would’ve been necessary to un-do the debt). Please let me know if I have misunderstood. 🙏🏼
I like this analogy. It's a great way to remember the rules but it does not explain why the mathematical symbols work the way that they do. I use analogies like this once I feel confident that my students understand the why.
@Ramy Melhem Naturally,if i have 6$ before I could payoff my debt and remain zero in savings. 👉I have debt of 6$ my friend paid off it now iam free of debt and I have zero amount with me. It's null zero, How is it positive practically? please explain.

It has never been explained to me that the first operator is essentially stating whether to add or subtract something and the second whether the thing being added or subtracted is positive or negative...I always thought of it more literally. In school, we were taught to accept that a negative times a negative is positive, but never why.
I'm happy I was able to make a difference in your understanding of negative multiplication. It's viewers like you who I appreciate. 🙏🙏 Let me know if you have any other questions.
I'm out of Debt = I feel GREAT 😊
🤔♥this video. Thank You.
After a lot of research this is the only video which made sense about negative times negative=positive. Best video ever about this topic. Loved it 💖
Thank you so much 🙏
How? He basically said subtracting from a negative is positive....i.e -5-5= 10 he basically proved that
Excellent!!!!! I will use this. Thank you so much.
awesome ... this video made my son quickly understood the mystery of negative multiply operation ... believe me it would be the most sad moment for any father in the world when you can"t find the answers of your child, thank you.
Jimmy Lukardy thanks for the feedback Jimmy. I am very happy to have been able to help. Please let me know if u have any topics ud like me to cover in the future.
Excellent video. This is what makes UA-cam cool. I love learning on YT and I love knowing that someone cared enough to explain this to the world. Thank you so much!
I love how you put it. 😍 Absolutely my pleasure.
best video to illustrate the idea !!!! BEST, been looking all over the internet for answers
Thank you, Curane!
finally at age of 38 years i understood why it iS like that . all these years i was trying to figure out why it is like that :D THANKS .
It makes me really happy reading these types of stories. Thank you, Mehraj. 🙏

Oh my god thank you. 34 and just started Uni and this is the basics and this one stumped me until this vid!!
This is genius!!! Thank you so much! Like you, I was trolling UA-cam, trying to find out WHY? WOW.
Last representation was much helpful and intuitive. Great work.
bro i am 13 years old and now i have realised that you are the best for explaning maths this is a basic but main question that everybody has and only few of us know thank you for explaning i have seen and asked many videos for this thanks you have got a new subscriber
@M.J-lb9zc thank you. You made my day ❤️
Thank you so much i am Ramesh from india,iam 50years old i was not undetstood when i was a student in school but thanks from your activity at least i will make my daughter doubts of why negative times negative is positive .
Thank you so much ❤️
Wow, that was amazing. Why tf can't this just be taught in elementary school.
because its boring

@@TKMKT1516 No, you are just a dumbass.
Became a programmer, never understood this concept deeply, just knew it works. Now i understand why. Thank you!
You made it so real man
Although I learned this years ago and just accepted it as how things are. The way you showed it, now adds the logic behind it. It really makes a lot of sense taught this way.
Most amazing illustration of negative times negative. Thank you so much.
Thank you very much.
This is best explanation... Thank you so much ...❤❤
Thank you. Even I understand! With your notation there is no place for confusion.
Алексей Воронцов Thank you
Thank you. The video made sense because you showed me the practicality of the math, not just told me a stupid rule to remember. Amazing teacher. You rock!
Thank you so much, David. Happy holidays to you and your family. 🙏
Thank you. I will be telling my tutor about you/videos. I know he will love your style of teaching, and I will continue watching you your videos.
@@DavidMorales-xo4uf thank you 🙏
If we only had teachers like you, math anxiety would not even exist
Excellent more of such videos sir 🙏🙏🙏
Wow! I was looking for a good youtube video to help me teach one of my students. Great job, this makes so much sense. Great job!
Thanks so much Amy. 🙏
I have had a learning disability since the second grade. I wanted to get my degree in Hospitality but the Algebra was not taught to understand in high school. I am using my 1 year off to learn Algebra before I take the course. I got stuck on neg x neg = positive. You explained it so well that I now fully understand the concept. You explained WHY it equals a positive. Thank you. Subscribed and shared.
thanks Sheila. u r awesome. good luck in your journey, and let me know if u have any math or science questions along the way. I will be happy to help.
This is amazing! Finally this makes sense! Thank you
Amazing.!.. that is the way to do it. Bet good money kids of all ages would love the style.
Thank you so much 🙏
Thanks Mr Melhem. I was struggling to explain the negative concept to my kids and your explanation helped greatly.
Great to hear, Jason. Let me know if you have any other mind-squirming math concepts that you'd like me to take on.
I was looking for a video for my students and this perfectly explained the concept. Wish I'd been shown this as a kid! Thank you!!
Thank you very much
Wow. What a great teacher.
Your explanation is awesome. Please explain why negative number divided by negative number is positive.
Very well explained makes sense. Thank you
Thank you for this video, it really helped me understand the logic of negative numbers.
That's genius 🔥
Luv the way you explained the things step by step with the real life examples, it's the best explanation I've ever received 🙌🏻
VERY GOOD...CONGRATS..EXPLAINED VERY WELL
This is totally brilliant! You’re a superb teacher.
Thank you very much 😊
In the ninth grade I took algebra, and in the first week I was lost. What submarined me was this multiplying a negative times negative and producing a positive. It made no sense to me, and I just could not get past it. I was completely lost the entire year. At that time I started telling myself a story that I was bad at math. I'm 65 now and have decided that that was just a story that I told myself and I don't know if I'm any good at math because after that first week in algebra, I avoided it like the plague.
So I got into my head to take a look at an introduction to algebra UA-cam video. And guess what happened. Five minutes into the video, once again it was WTF? But this time I decided I was going to get an answer. I've been through a dozen different explanations, and this is the first time that it's actually made sense. If you were here I'd reach out and hug you. This is a brilliant explanation
Virtual hug, Lance. 👐 Thanks for taking the time to share your story with me. That means a lot to me. Im really happy that i was able to shed some light upon this topic. Unfortunately too many students are in the same boat, blindly following the math rules given to them.
Thank you again 🙏
If you have any further questions, then please let me know.
This is so awesome he is such a critical thinker ❤️❤️
Well done. Great teacher🎉🎉
I've known since primary school the "rule" for negative x negative and I have watched this and many other videos on this.. but my logic was the answer is the difference between the "starting point" being a negative and how many places it would move in the positive direction. Which would make the new position zero and the difference between that was +6. Is this right? The answer is just the difference between the starting and end point/sum? Rather than literally going from negative nothing to positive something which would mean a movement of +12 which is what I think mixes people? Rewording my clarification, the negative x negative equation is only giving the total movements and not the literal new position or total of "things" or "dollars"..?
Your logic is spot on
wow! i'm old and have trird to find the answer to this since middle school, NO ONE has ever explained it. I feel like life's greatest mystery has been sovled thank you. instantly sub'ing based off of this video.
Wow, thank you very much.
Ramy, since so many ppl are sharing their age, I’ll just say a couple of things:
1) I’m a week shy of the 4th decade, reasonably well-educated, and I never quite understood the “why” for this problem until today. I figured out part of it out on my own in the morning, but your video rounded out the day in spectacular fashion for me. Thank you.
2). If I may just point out, that re the end of the video, the final result of the positive $6 is NOT the $6 he made from mowing lawns. Rather, it’s the $6 came from the bff (that would’ve been necessary to un-do the debt). Please let me know if I have misunderstood. 🙏🏼
Happy belated birthday. Sorry for seeing this comment so late. Yes you got it right.
Thanks for this video!! Finally why (-)x(-)= +, made sense!! Great video. Keep up the good teaching! 👍🏼
Interesting and memorable way to present this, and great format!
Thanks very much
Thanks for the awesome lesson!
Thank you Heather. I appreciate it. 🙏
Best video explaining this. Thanks
your explanation is magic. thanks. I am going back to school to learn math and drawing.This should help.
Thank you. Let me know of you ever have any math or science questions.
Love +
Hate -
Love to love = Love
Love to hate = Hate
Hate to love = Hate
Hate to hate = Love
I like this analogy. It's a great way to remember the rules but it does not explain why the mathematical symbols work the way that they do. I use analogies like this once I feel confident that my students understand the why.
If someone smacks you in the face, and then you hit him back that going to make you feel positive.
dividing negative fractions...go! oh this was helpful btw. thanks
This was perfect. What a great way to explain it. Subscribed for sheer awesomeness.
Thanks for subscribing. I haven't made any content for years now, but comments like this definitely motivate me to want to make a return.
This explanation is INSANE!! This is so clear!
Thank you, John. 👌
This is so wonderful! Thank you! Such a difficult concept to explain, but you did such a great job doing it.
Thanks very much
@Ramy Melhem Naturally,if i have 6$ before I could payoff my debt and remain zero in savings.
👉I have debt of 6$ my friend paid off it now iam free of debt and I have zero amount with me.
It's null zero,
How is it positive practically? please explain.
Best math vid I came across in a while. Good job man!
Thank you, Esteban. 🙏
Well done! From a retired maths lecturer in South Africa. The best I have ever seen.
Thanks a lot, sir. I really appreciate it.
Awesome explanation, thank you so much
Now I understand 😀it really bugged me. Thanks a lot.
Thank you for your effort bro! many people understand what this mystery means. it's like negative times negative = Blessing
Nice concrete example of why negative x negative = positive.
The BEST explanation about this topics all around the world till now, although I could not become satisfied to the logic. I have slight different logic on it,
Thank you.Would love to hear your logic.
Hell yeah ! Awesome
