If your X comes back
Remember to ask Y
Raya....hahahaha...lol..
LOL too bad its a real problem.
Raya looool
Y are you so X-tra (im not saying that u r extra, im just trying to make a joke, sadly, my joke is bad)
That was so cringy
Dear math:
I'm not a therapist.
Solve your own problems
hhahah
Nice
I'm a tree haha funny plz give me likes lol 😂

lmao the 500 people that disliked this video were all teachers.
bruh i'm not surprised they're jelous
its cuz this is the normal way
Yeah.. this is basically the normal way to solve them. All it did was display it differently and have an attention grabbing thumbnail.

I learnt more in 10 minutes and 14 seconds than 4 weeks in school LOL
Nice
We are now living in a better era. I mean teachers love making it hard like there job is to teach you. it's purposely have to be confusing so students wont take over.
Lame(2) 😂😂 cross multiplication is better than this😂
What grade are u in?
We learned this in grade 9.. maybe even 8... u must be like 10 years old?
Mind Blown!
I have always struggled with math. I wish that they taught these tricks in school
many teachers suck
@@toddlavigne6441 So true
They do teach this in school.. this is literally basic math. Where did u go to school?
@@diyaasaeed7959 Lucky you. I wasn't fortunate enough to have teachers who taught well. They just expected us to understand.
@@jasmineandstewie1271 I agree. I guess we are lucky but this should be considered basic curriculum to even pass high school. Algebra like this starts in middle school.
You sound like Bruce the shark from nemo!
I love this guy but since you said that I imagine a shark now! XD
Lol
?
GAMINGwithHENRY that's soo true😂😂
LOL
I've learned more in 4 minutes in this video than my whole semester in my high school algebra class
Same 😂
I used to struggle on algebra now I'm finding it bit easy now cuz doing an algebra you really need to understand it
Wait algebra is a high school course? I took it in 7th grade
same
Fr tho
What's the point of school when I can learn it here in 10000% less time
ChetanPvP I agree
At school you learn to do it by heart through cramming, here you're just going to forget it by the next day.
uneliasmarsu false...Here I LEARNED IT....at school it was crammed for a test
Fr,I'm tired of going to school for years. Like when I can I have a life thats fun
Hello you have to understand this stuff because you will need this in college or wherever. Teachers teach you to understand the structure of something like that. This is one of the most important thinks in maths .You just get prepared for real maths in school.
If schools taught this we would have flying cars by now
they don't teach you guys these?
daniel b they teach us these in hong kong
I think he meant "thaught us this way" so people actually understand the concept.
7.2=3x+5
14=3x+5
9=3x
x=3
they do.
I’ve never been one to understand math or do it easily but after watching this video it was a life saver thank you so much you really helped me!
cool dude
Really that easy? So why does school made it look so difficult?..hahahaha..this helps a lot..thanks dude :)
Don't call him dude call him sir
he sounds like hes baked. baked with knowledge. Lmao
ooooooohhhh
hell yeah he is.
Miguel Gonzales He's high on math.
is that supposed to be compliment because it didn't sound like it.
it's not really nice for some of you people making fun of smart people and calling them names (nerd or whatever), at least they are more independent and struggle less at certain things. if your knowledge is not enough to reach them then you should probably keep your mouth shut!
Dude its a compliment. Im saying hes really smart and this actaully helped me passed a class
This guy is the best teacher and I've been watching him since 2011 and he made me get min 80% in test.I owe him so much.
do I are
Agreed - I use his videos for my 6yo and 10 yo and myself - they're my absolute favorite way to learn math. His students are so, so lucky. Keep up the great work, tecmath!
Ray Mamo for real?? Will he help me? I’m failing in maths so much. We had a test today and I got 17%, I swear I’m not joking. Need a solution and fast.
He is the worse, his method is wrong, it's mathematically just not correct, see my comment for the info, à little above
before i discovered this guy i got min 85%, now im excited for my next result.
You have a voice for audio books. I can imagine you reading a children’s book 😊(no hate comment!)
Yh!
After having a breakdown due to algebra earlier I stumbled across your video and all I have to say is God bless You!
Dear Algebra,
Stop telling us to find your X
She's never coming back.
And don't even ask Y
lol longer version :D
Haha
copied comment.
Dude. I almost wanted to cry because this was so hard for me in school and you made it easy to understand. Just an older guy who decided to to try an re-learn this stuff. Thanks.
God bless you all!
Why couldn't you have been my teacher in math? Omg they were so awful , I actually understand what you're doing
kawaiikowai08, same! I agree! our normal teacher a
is great! but we hade a substitute the day we where supposed to learn this and I DIDN'T UNDERSTAND ANYTHING!!!! but now I might do just fine on the math test tomorrow 😃 aka in 13 hours!
True i am the worst at maths
Monika Gandhi z
This method is wrong, see my comment a little bit above for explenation
Omg you just made this so damn easy I have to take my ged test in three weeks omg thanks happy I got this opportunity but I have one question are you still doing oder of operation when you revising
This teaches me more in 10miutes than how my teacher tried teaching me for 3-4 months
to learn only that you needed 4 months? OMG get a new brain! lmao
Lol

Nicely done. I love the attitude. I as adult student at 52 fell in love with Maths. Now 70 and still trying to learn. I watch your videos over and over again and as soon as you write the numbers I try and work it out first. Before seeing these videos, I may as well have been looking into a ditch. Keep it up sir........
Liam Kins Thanks for the comment! If you love the maths the numberphile channel is pretty good too! Full of interesting stuff.
It's never late to learn math. Still trying myself. Won't give up. Hopefully! Congratulations!
+Pomonoli NO insult taken. I just studied the maths for 2 years, until the examination, which I passed, having never even heard of an X squared, or algebra. Now, After the exam, I hadnt used or had reason to use maths until roughly 1 year ago when I saw some featured videos about them on the internet. I am not studying for 18 years, I had forgotten all I learned in my 50s. Great to get back to them, even if it is just for passing time, and keeping the old brain alive. Thank you for your reply.
+Pomonoli tec's videos aren't meant to teach math, they're for speeding up the processes that go on in your brain. In an algebra 2 class I'm still looking at the addition and subtraction videos... lol
M'y daughter Don't understand make it easy for Her and others
this guy even taught me a quicker way to write the letter X
Haha
Ryan Garza That's the way that the Japanese write their x's, because it resembles Kanji strokes.

Where were you when I was a kid? Oh yeah; the internet had not been invented yet! Your videos are helping my kids a great deal. Thanks.
Thank you kindly mr. Techmat.
I'm 45 yrs old . I have struggles in math in my childhood. But now I can understand it easily and enjoy learning. Happy to subscribe here in your channel. .my daughter is growing up. Ill teach her the basic . Rule and law in math..
Things are very simplified here with your teaching.. Jesus bless you sir. Salute and hats off to you.
What ever teacher teaches in school I didn't understand but this teacher teaches is so excellent
Glad to have helped
There is nothing wrong with him being smart on math. Its nice i wish i was smart as him
JiminGot Jams Jimin really does have jams 💜 army
Army learn Maths now
I'm so blown 🙄 the entire time I've struggled with the quadratic formula when I could've just done this!
why the heck can i understand you but not my original math teacher like jesus christ.
Mindy Hills 😂😂😂
I'm the same way too
BECAUSE YOU WERE NOT MATURE AND FOCUSSED
Idk about you but I have a hard time understanding mine because whenever she teaches it sounds like she is talking in a sarcastic "ur dhmb" voice
*THIS COMMENT IS BASED ON MY OPINION*
I think I have to same problem too. I don't understand my original math teacher but I understand this guy. I think it's because of the screen. You see, a few people will pay attention to their screen then in class.
1:15 wrong! there is missing a bracked
I feel like you just cheated and hacked algebra, cause someone so clueless like me understands and learned so clearly, this is the best lesson Ive seen on youtube by far.
actually this is the how normal of solving algebraic questions I think
Yeah he just made it for weak students
Harsha Shah more like special ed students lmao
OMG!!! This guy is awesome, for the first time ever I have figure out how to solve equations the easy way, man... I have never been so happy in learning something new in all my life. I was so overwhelm with excitement after he presented the first problem that I was able to pause the video and work out the remainder of video questions before he reveal the steps and the answer and I got them all right and analyze them the same way he did. I am indeed very happy and proud I've learn a new way of solving math problems.
Aston Rain hey me too! I would send a pic of my work but yea.....

Thank you so much I was never taught algebra and am now expected to solve equations such like these. Your a real life saver.
I love your channel because it helps a lot in tests.
(THUMBS UP) :)
This is exactly the same as normal equation solving. You just used another notation. I don't really think it makes things any faster, you still have to know how to inverse the operations. You can solve all of them fast and without much effort using the "standard method".
(5x - 8) / 3 = 4
5x - 8 = 4 * 3
5x = 4 * 3 + 8
x = (4 * 3 + 8) / 5
x = 4
It's all just basic algebra.
Agree.
Only people who aren't good at maths think this is genius
Good luck convincing my math teacher of this. You do it differently than they taught, you're marked wrong.
Melita de Rond He’s doing the exact same thing that was taught. People who understand this but not their teachers are just not paying attention.
You can tell your teacher that you are genius if you learn this
Is it inappropriate to say I love you, you have just saved me from the stress of my math class. I always knew math is not hard , it's just understanding it. You have given me confidence, all the confidence that my college math classic have stripped away from me. I am on anxiety medication because I felt like ..... Let's just say not understanding my class work was slowly killing me. Thank you for saving me. I really feel as if you just saved my life. I almost drowned in a lake when I was younger, I was blessed enough to be saved. Even that can not compare to that you have done to restore my confidence in my ability to understand this math. Thank you so very much.!!!!
@Terrick Lawrence sorry was my brother
sorry about the rude message my brother wrote it very sorry
Dear algebra
Stop telling us to find x
She not coming back
I really don't see the problem? You just need to bring both sides to a common denominator ( (3x+5):7 = 14:7 ) then just throw it away ( 3x+5 = 14 ) and you get the usual linear equation -> 3x = 14-5 -> 3x = 9 -> x = 9:3 -> x = 3
This is very easy and takes no more than 5 sec to solve. Maybe in US you people were taught a different way of solving this?
Because its less efficient with numbers that aren't integers
Solving Backwards
Im from India and i solve it your way... some people i the comment section said he needed 4 months just to learn this., lmao

Stop telling as to find your X,and don't ask Y
Ning Ngi Ning Ok!!! Getting a lil old ya think!!!?
Copy cat
ok how old
THIS ISNT A TRICK THIS IS LEGIT INVERSE OPERATION
Make you smart everyday Smarties well what is your definition of a math trick? Everything is explained by math but some ways are easier than others
I don't know what teachers are teaching, but this is general math knowledge
thank you so much! ive always just put in random numbers to find the answers
Not sure if anyone else mentioned it, but in the problem you worked from 4:15-5:54 there should have been 2 solutions. x= -3 also works.
Problem with that is if you did that in an exam you'd fail for not showing your workings correctly.
That is so true
Thank you Bruce sincerely Nemo!
Me: plays algebra video for the exam
Tecmath: "Goodoy m8"
Me getting a flashback in 4 grade when I saw a vid of him teaching me to do minus and plus
I love this channel. These tricks make it a snap. This video was just as helpful as percentages and fractions.
Omg, you're a genius really!
I used to suffer so bad with my maths, always going to extra maths lessons and being a dissapointment to my math teachers. I was actually really bad, everyone used to laugh whenever I gave an answer out so I just stopped trying. I stressed so much about it that I began to fail my other lessons too. After watching this particular video I carried on and on the playlist and as cheesy as it sounds I'm glad to say that even my math teacher said she was impressed! Thank you so so so much! If only you were my actual teacher!
Same
Thanks for sharing your experience 😊
I wish this guy had been my algebra teacher in high school. I would have done great. Glad I've found his channel. Thanks for posting.
Dear Board of Education,
So am I
I had Allegra I & II in high school a hundred years ago. Haven’t thought about algebra in over 30 yrs. now I gotta past a test for a position at work that includes algebra. Nobody made algebra sound this easy. God bless you man. I appreciate you😊
It’s 2019 and THIS REALLY HELPED
this 2020 and it STILL HELPED
Juhaina Basaleh Same! :D
Will maths change over time?
Thank you so much, damn my teachers teach my a whole different way and I couldnt get it right and we both were frustrated... now you just helped me ALOT thanks so much!
Which part of England are you from?
South.....really far south.......(in Australia!) :)
tecmath Hahaha! Nice replied, that is really far south of England ;)
However, cool video man.
Got to love that accent, hehe. It is unusual not listening to Americans or British people talking on youtube.
tecmath I really find what you are doing to be awsome! As for the haters and to smart for their own good people,"ignore them". I have learned a lot from you. Thank you.
I really hate algebra it's cause of my stress and give me alots of problems with every day.
You forgot to put the parentheses. People end up getting wrong the operation priorities by misunderstanding examples like this.
Overall it's nice to have a look into other ways of solving it. But it makes sense to me to still write the intermediary steps to solve x, since it helps me and others to visualise my work.
OMG I FINALLY UNDERSTAND IT . You are legit the best.
this guys a freakin genius he belongs at Harvard or something
nice job unwrapping the order of operations here
you are a freaking genius!!!!!!!!

If you cant solve the equation in the thumbnail in less than 10 sec you probably need to watch the video🤣
This is how you're taught to solve it. Nothing's new here.
Hitopopamus I guess you got taught better
depends on how and by who you are taught it by
No it's not its literay how you do it
@@Divine.777 bet you wish you had a better english teacher
@@monogamyisforslaves3867 oooooof🤣
√9 = +3, -3
Am I right?
yes!!
that is the principal root
yes you are right, plug it back in and it still works so you are right
Yarubiks66 Just because it works doesn’t mean that _/9 = +_3, yes the solutions are +_ _/9 = +_3 but the square root of 9 is just only 3
x^2 = 9
Take the square root of both sides
| x | = 3
Then,
It’s either x = 3 or -x = 3
As a shortcut, we do this :
| x | = 3
x = +_3
So that’s why,
x^2 = 9
x = +_3
There are missing steps as a shortcut, but _/9 is always 3, since the definition of _/ is the principle root
Isn't this just exactly how you do it the normal way...
It's a better way to do it in your head
Exactly!
THIS HAS CHANGED MY LIFE OMG!!!
Took me one time to watch one part that is 10 seconds I feel like the second Einstein
also. your voice is very soothing and relaxing. it makes me wanna learn math even more.
Before i really hate Math, but now luv luv luv, thank you for this vedeo more vedeos please!!!
Im in my 80's, and have been learning some of the stuff I could never understand when at school (or since). How I wish I had, had teachers of this guys ability. PLUS, this is the first time I realised, that Square root is the opposite of squared! thank you
Mmh
when you done that evil equation with the root, you sounded like a child on christmas morning :) thanks
What if there's another variable in the equation?
For example: X + 4x - 4 = 17
YOOOOOOOOO I LITERALLY WAS SO CONFUSED IN MY MATH CLASS AND THIS METHOD IS SO MUCH MORE EASIER!!!!!!!!!!
Nice explaining, my teacher goes way to fast in math so I always like to learn it at home. If I don't get something in the video, I can keep going back until I understand.
Smart Panda same
That's not easier. Here's the way that I would do it:
3x+5
---------- = 2
7
7x2=3x+5
14 = 3x+5
14-5=3x
9=3x
x=3
That’s exactly what he did dumbass. You literally just copied his every action. The equation was written as (3x+5)/7. The guy in the video then inversed the operation to get (2*7-5)/3. You inversed the operation to get (2*7-5)/3. All you did was write it out more.
The way you did it was the exact reason I flunked math so many times that I gave up on my degree. Now if I can get a current textbook and match up the problem types, I can learn on my own and hopefully audit out of the class without all the unnecessary confusion.
This is awesome!!! Thanku so much sir! :) never thought, it could be done in this amazing way....so happy...😊😊
Thank you soooooo much!!!!..🌈You are an Amazing Brillant SuperTeacher!!! 🤩
thank u so much
I got 50/50 a test, coz you helped. What you did in 10mins the teacher did I 2 months. Why can't we learn watching UA-cam? Less time, Less fuss.
Isn't this "trick" just a variation of the usual way to solve those problems?
To find x, you need to reverse the order of operations, that is the description of the problem. What new information is added here?
It's really not my intention to be mean, I'm sure that it's helpful to someone who doesn't know how to solve those problems, but it doesn't add anything to those who do. Or did I miss something?
monganni It says "shortcut trick" in the title.
ChilledfishStick I believe the point is many have been taught to do it the old way from left to right which obviously requires more steps hence the term shortcut and the trick of reversing the operators thus simplifying the equation.
Dharri I'm not sure it does take more steps. It is essencially (11*2+3)/5.
Your explenation does make sense, I'm just not sure it's a good trick.
It may also be individualistic terms of what works for one person vs. another. The concepts are good either way.
ChilledfishStick Well i think it's a fantastic trick. (revelatory in fact) Isn't the single most important thing; is that people learn from this, and not whether you think it's a 'good trick' or not? Of course if you're wise to the teachings here you won't be enamoured with the method. And yes, you did miss something - if somebody didn't know how to solve these types of equations, but after watching this video they now do, then this video has been a total success. Pedant!
Awesome job but man you’re “X” is driving me nuts 😂
I've come to like it. All I saw at first were "c"'s. BUT I know it is good for my brain to SEE things differently, I think I might start doing mine like that too! :D New connections = brain exercised
They're done like that so they're not mistaken for a times sign :P
@xXAnimeLover ForeverXx I think she was making an 'ex' joke
The same can be said about your grammar, "you're X". LOL
Most excellent!!! Hope I can pass the gace now!
Im genuinely saddened that in school i did not learn it this way. I learned a overtly complicated way that i just never could retain. I always felt like my teachers were just being smug and carless with the way they tought , no regardes if anyone got how to solve the problems. I wish it was taught this way .
I don’t understand, what is the trick your teaching is basic algebra they teach everywhere
Define trick. What we're you expecting?
Dear algebra, grow up and learn how to solve your problems.

To learn Algebra, you pretty much have to take all the maths you learnt up until high school and throw it out the window
This is so complex! It can be done in much a simpler and faster way
This video is amazing! I loved the giggles 😂
OMFG why did my math teacher not teach me this way!!!!! i have always had trouble with equations until now omg thank you so so so much!!!!
Is this working out acceptable for marks in tests?
TheCowzy it depends. If the question is only multiple alternatives, yes.
Thank you for teaching
I struggled to understand and reconcile this with more traditional methods and came up with multiplying the answer (2) by the divisor in the equation (7) to get 14. Then I was left with 3x plus 5 = 14, so 3x = 14 minus 5 =9, so x = 3. Does this always work? Am I just slow and struggled too much, or is this it?
That was great unfortunately my short term memory dictates me watching it over and over again to get it to stick, however, that was very easy, just not easy for me to remember. Great job
I solved this mentally in my head before he started solving it...
I remember one time my math teacher said, "Algebra...is your bruh."
What 😅
Most teachers will give you an equation like that but wont tell you to find the value of x to get the correct answer.
I got a 5 mark question on this did ur method got 3 marks for the right answer lost 2 for wrong working out wtf
