Wow 30 year's I thought I was dumb and bad at math, but 5 minutes in this guy got me doing algebra in my head. Good job my guy
These instructions makes everything so MUCH easier!
Love this channel!
It's not any quicker. It's the same.
@@ytsux9259 I've read your other comment on how you use a calculator.
Are you trolling? Or are you seeking attention?
You just simplify Algebra in 5 minutes, that my teacher couldn’t do in 2 semester 👍
Hahahaha LOL
Maybe you weren’t paying attention and didn’t take the initiative to learn it? 🤷🏽
Sooo true !!
@@tomsis3825 Maybe the teacher(most likely) is shut.
ha!
This channel is amazing. I’m 24 and have wanted to better educate myself in mathematics for a while and the techniques/way you explain things makes the learning experience very informative, but also a lot of fun! Not an easy task to accomplish, so thank you for these videos and the hard work that’s put into them 😁
They should broadcast this stuff in classes. If I had this type of teaching given to me back in school my maths would be great
I have had terrible moments of trying to learn math all of my life. At one point when I was eight, my mother would physically hit me with a ruler if I got the answer wrong. I feared and hated math! This channel has made me excited that I can ACTUALLY do it! Thank you 🙏❤️
I had a teacher, well she thought she was. Left me in a room to figure out a math problem, told me I couldn't leave till I figured it out. I left and the problem stayed.
I’m East Indian here but this what exactly we were doing in our algebra class 6th grade 2010.
This so basic I don’t feel this as a trick!
Other countries made it so complicated
So true. In Trinidad and Tobago we have it nice then because start these when we are like 11 or 12yrs officially
The simultaneous trick was absolutely brilliant!
I believe that the capability to learning about anything relies on a couple of different factors;
1) Possessing at least average intelligence in order to be able to learn, comprehend, and retain the principles involved.
2) Certain subjects are more easily learned by the side of the brain that is better able to comprehend that particular subject matter. In other words, it's a left brain, right brain situation. Math comes easily to some, but not the ability to drive a car in a safe, effective manner.
3) There's also the fact that HOW a subject is taught or explained makes a big difference in the subject matter being learned and understood so that it can then be implemented by those of us of average intelligence.
👍
No way I just spent two hours watching this channel... call me a nerd but I love math
Same😳
Haven't done Algebra in 53 years... I understood it then and enjoyed it knowing what you do on one side of the equation, you do on the other... I received good grades, but the memory has left me... seemed confusing some of it. If I saw it done old school style, it may ring a bell! HA! Good teacher - been watching some of your other videos just to see what I remembered... much, to my surprise at 68. Loved math! Thank you for sharing & have a Happy Thanksgiving from a grateful California gramma 😄🌴🌺
This is brilliant! Thank you for all the hard work you do.
Wow, have struggled with algebra my entire life and this simplified it wonderfully
When did Bruce from finding Nemo start teaching algebra.
Anyway this is awesome great video
This trick was taught by the textbook in 8 or 9th grade it helped me understand it really well. I really enjoy watching your videos even the ones i know ,bc it really engages my mind and strengthens the basics.
This channel is amazing! I always loved math but found algebra and geometry challenging. This simplifies it in a way that makes me want to learn it more and get better at it ❤
This explains everything in easily remembered methods.
Great short cut. Thanks!
I don't understand why my teachers aren't at least half like this guy
thanks for the help and support
Thanks for your amazing Video :)
Always learn something new or reinforce something I've learnt :)
Happy to hear that!
Agreed - so much to learn from these videos!
I’m really impressed by the quality of video, can you let me know what are the tools you are using for recording videos ?
thank you for this video, this helped me so much
Thank you very much 🤜🏽
Great Video 👌
I wish you had a million subscribers, you make us understand it soo well. Thanks and keep up your hard work 😎
He does now! :)
Work smarter, not harder!
Where were you in the 80’s when I was crashing and burning on algebra
I love it!
That is an example of knowledge denied in maths classes.
Thanku so much. it's very useful for me to use it in my competitive exam. Love from india.
Thanks
Also watched your trigonometry video and man was that so simplified
Mr. Shortcutter..
I like how you simplify math..
This such fun!
New subscriber .. Ty
thanks
Goshh!! 😳You are definitely an AMAZING TEACHER🤩🤩🤩 ...Thank you soooooooooo much!!!!! All ur short cuts is just Wooow!!!“FANTASTIC”🤩🤩🤩
Will get this jumper tecmath..🌈soon..
you're really best teacher,i did subscribed you todat thanks for helping us. I am sure you helping alot of parent's like me,i came here to refresh my math so i can help my children with their homework.🏆🏆
Please continue
Is it just me or his voice made me forget what I just learned 🤣
Wow....call me gobsmacked! I could have actually had a better time in high school math! All these wasted years....
Very good I need you when I was going to school 😂 lol
Nice
That's not a shortcut, that IS how you solve algebraic equations!!
Wow this is better then school
Another way to do 2 equations with 2 variables fast is by turning the equations into an addition and cancel one of the variables during the addition process. In the last example you can multiply the upper equation by 1.5 so as to turn the 2y into a 3y.
Thus...
4.5x + 3y = 10.5
5x - 3y = 37
Now think about the two equations as a big addition in which you add the X values individually, the y values undividually, and the constant values individually:
4.5x + 3y = 10.5
+
5x - 3y = 37
___________________
The Y values will be cancelled. So we add the x values and the constant values:
4.5x + 3y = 10.5
+
5x - 3y = 37
___________________
9.5x = 47.5
Now we solve for X:
x = 47.5/9.5
X = 5
Now we solve for Y:
5(5) -3y = 37
25 - 3y = 37
-3y = 12
y = -4
I think that's a faster method, except you have to deal with divisions of decimals. The caveat is having no negative or no positive variables. Then you need to multiply one of the equations by a negative number so as to be able to cancel one of the variables.
Amazing
I struggled so hard through chem 1 and 2 for my BA. I had the worst algebra teacher my freshman year of highschool and ive had a hard time with math ever since.
THis is great sir
sir could u do tricks on all types of partial fractions, please.
Of course he can't Haha
There are many who are interested in maths not because of academic/professional reasons but for hobby, or overcoming a childhood fear. It's untapped territory for maths UA-camrs.
I wish the teachers in the 90’s would have explained it this easily
How about X/Y = ? Thanks for sharing your knowledge👍🏼👍🏼
plz upload a video on trachtenberg speed math methods...
Good
Bob Ross of mathematics.
i thought i was dumb in my school years, that last problem confirm that i still am.
in the third shortcut you solved for x and then put in the x value to calculate what y is, not that this question really matters but im curious how you would solve for y first using the same trick?
@@clenel i think its starting to click in my head now thx
@@clenel ohhhhhhhhhhhhhhhhhhhh now its really clicking in my head, thank you a lot. I see what you mean by "connect together" now ;)
Legend thank you my bro is dumb so thx 🙏
👍👍👍👍 nice
Hi Tecmath, in the second and third shortcuts how do you know when to add or subtract and and how do you know if your dealing with a positive or negative number. This may be a stupid question but I got lost on facets of the last two !!!!
You just subtract. Put the coefficients with the sign (+,-)
That'll give u the ans
Eg, in 3rd one, (2×37) - [7×(-3)]
Will give you (2×37) + (7×3)
@@tanishijain8019 much appreciated could you expand on your answer please 🙏
Love New Zealand
These are the ways I learned from childhood is there any ways else that I dont know despite of having master degree?
I thought that these were tought in every school
@Ruairi Burns yeah I think it’s a thing in The UK and Ireland. I was so confused cos I saw the square root trick and was blown away and came to this video expecting the same types. When I checked the comments everyone was saying it blew them away and I was taught them straight away in secondary school.
Judging by your spelling, I don't think so.
Equation shortcuts.... and isn't this rote learning an algorithm without understanding balancing equations?
Waoo, got it
this is stuff i learned in year 7???
I think it’s just cos this is an American or Australian channel. I’m from the UK and learnt all this in year 7 too
So am I , is there any other ways ?
does the first trick work for everything?
Bro i done algebra all through year 8 and didnt understand a single thing about it that was last year im in year nine now and school jasnt started but now i know how to do two step algebra when before i couldne even do one step
I Saw This Shortcut Before 7 Years of ur Video
First two I completely get. The last one isn’t sinking in 🤔
Simultaneous equations is similar to the butterfly/cross multiply technique. Also, don't forget that you are crossing over the = sign. Then on the left of the =. the + becomes - and the - becomes a +
Re-watch the 3rd method carefully.
Thanks D J Kav I’ll keep working on it 😃
Make some basic geometry and basic trigonometry test, and teach us, how it solved and how it works make for us some example solution or basic solution, for that…thank you I hope to notice my request
one problem is that sometimes it's easier to find the value of one variable than it is to solve for x, especially if the fraction doesn't always come out perfectly.
do you have a book?
Sometimes,
A1 needs to just let 2b so that 3 can c the 4D.
What say you my friends ???
Hi
No hi
Hi
Can you show me how these apply to real life?
It's called school, and you need these shortcuts to speedrun tests and exams
1:00 You forgot your parenthesis
You won't need it if you wrote the numbers in the right order.
Bro you is god
Counterintuitive mathematics
After u showed the first problem, I wanted to drop my phone like they drop mics. Get out of here omg wow lol
Y you can't x everything inside the bracket by 2. Only 2 x 3. Y?
can you make one for fractions? Thanks
-EpicGrowtopian
I mean, you can do the same, for example : 1/3 = 1:3
7:35 why subtraction and not addition???
uhmm I have this problem in my head and it won't go away because I am not sure if my answer is correct sooo can you please help me.....
the Problem
If one ream of bond paper costs
(x - 4) dollars. How many reams can you buy for
(6x⁴ - 17x³ + 24x² - 34x + 24) dollars?
Division problem...
(6x⁴ - 17x³ + 24x² - 34x + 24) /(x-4)
= 6x^3 - 7x^2 + 52x - 174x + 720/(x-4)
Might want to check me on that.
now i can beat my friends thanks
I can solve them faster with out this method
But it's beautiful way to solve 🌸
no one asked
I learned this like in 6. Grade and everyone says the German school system is bad (it is)
I fail twice never had good teachers in my school year
Wait isn't this just algebra? How do they teach it in school? This is what I always did? I'm not being facetious I'm actually curious how they teach ir
You had to slowly move the non x numbers to the other side until x is isolated.
@@spannycat2 that's what he's doing though? He's just condensing a bunch of steps into one. Like the first trick, what else do you do? I look at those expression and in my head I collapse all the steps very quickly but it's the same fundamental process. You're just isolating x since you're solving for x. Do you mean that they explicitly made u write all the steps verbosely and rewrite the equation?
@@TranscendentPhoenix I mean like the teacher wants us to show our work or we get docked.
Hey how to solve 2-3x/4=5 by this method...?
Just write the problem as you read the problem. Then, read it backwards.
For example, 5 times 4 minus 2 divided by -3. Check it, you should get x = -6.
Can someone explain what he did here? Im a little confused: 7:10
Idk if you're gonna see this, but:
Since anything multiplied by 1 equals itself, you can just write a 1 before it (to multiply) and use it to solve the equation later on.
@@furqanahmad8882 Well I knew that, I was more confused about what happened when he crossed the variables to answer the equation. (Thank you for taking your time to answer my question tho :)
Wait! At 5:20 on to the end of that particular example, you SUBTRACTED 2 from 6 and totaled 8. Did you make a mistake and/or is that the part of the problem and reason why I had such a difficult time learning math in school? 😲
He subtracted 2 from negative 6. That’s why it’s negative 8.
I love how people on the internet think this is a math "trick."
All it really is is reading the problem forwards and backwards. We all did this back in the 3rd grade. We did 3 + 2 and we got 5. Then, we did 5 - 2 to get us back to 2.
Every problem involving the 4 operations is like this. Read an addition problem forwards, then use subtraction to go backwards. Read a multiplication problem forwards, then use division to go backwards.

Please how you got y was too fast
How is -3 20 i dont get it
👏👏👏👏🙏🙏👏👏👏👏👏
Clear as mid don’t understand any of it, guess I’m too thick.
