wow wouldn't of picked this up :)

:OOO didnt even realise

Yeah ikr, I love how people say "they dojt teach this in the schools" where they have been taught about this since 6th grade itself. Took me only a few seconds, when he said "twice the number"

no it isnt

@@scottcaine4514 yes it is

🤣

😭😭😭

no cap lol

Wow this fact made me laugh

True

Textbooks and homework is what students had prior or before podcasting was available. The results reflect the difference in performance by the students!.

Not at all. School system has a different purpose which is to teach you the concepts. Whereas, these shortcuts which are a distilled form of those concepts serve a different purpose, which is to make your calculations faster. Both have their place.

No.

Pls solve 798² bro

I didn't get it.

@Ed EdwardsThat’s apart of the American dialect. It is not a typo

for me it feels likes he's on the verge of laughing out loud

Most accurate observation ever...

Now I'm yawning when I hear him speak. 🤭

For me it sounds like he´s about to giggle all of the time

Those who say "I can't do math" have never seen these techniques because they don't enjoy doing maths. They also wouldn't think this is fun to play around with.

They do teach this people are just too dumb to apply it to real life this is (a+b)^2 it’s taught in 6th grade in most places

😅Bruh same

Thanks mate

@@tecmath 👍

That's not a gift,that's simply (a+b)^2

@@arwen3478 you use (a+b+c)^2 lmao whats wrong

@@karenamma7716 you wont be able to tell that if this video havent told you about this in the first place lul

Can you explain the last part in pyramid form?

works with 5 digits too

yea its fun when they look at u how fast u have done this but actually we r using these tricks to do faster .... :)

Literally. Good observation

he told that already like twice

@@tecmath To justify no idea because I have not learned algebra yet

Go to 4D space time by AK science

Yes it’s (a+b)^2

That’s nice. Been using it for a long time myself. You can do larger numbers if you adapt it slightly - see my videos on my channel if you would like!

Nice method

Yes!

This is simple algebra

Thanks for the mini-biography

Lol

Sorry to reply lateeeeee

My call was 367

632²=360000+900+4+36000+2400+120=399424 there ya go. It's an old mathematical trick. Not hard at all. It's so old that I bet all of you actually knew it before the video, without realizing it. (a+b) × (a+b) = a²+2ab+b² It holds true no matter which base you use. And let's show an example of 23² = 20² + 2×20×3 + 3² or 400+120+9 aka 529. It's how everyone turns big multiplications into smaller ones. 322*345 is difficult but 300*345 + 20*345 + 2*345 looks a lot easier and 300*300 + 300*40 + 300*5 + 20*300 + 20*40 + 20*5 + 2*300 + 2*40 + 2*5 looks even simpler to do. And for the sake of answering that it's 90000+12000+1500+6000+800+100+600+80+10 or 111090. It's exactly the same principle.

I was stunned I got 362 as my guess!!!! xxxx

@@livedandletdie Feeling a dimmy wit at the 2ab stage as to me that is doubling and not squaring. Maths always was my weakest subject and still is along with needlework!!! xxxx

@@janemccourt5022 My needlework needs improvement, thankfully my maths is very good.

The order of the calculations is important as it relates to the tens column that the answer should be in. For example 60*60=3600 2*(60*7)=840 7*7=49. However by using commas to denote the separation between the powers of 10 (lets call them open numbers) it enables one to handle the multiplication of any number of digits provided the correct sequence of numbers that are multiplied together are added together. In this case it would be 6*6=36, 2*(6*7)=84, 7*7=49 giving the open number result 36,84,49. From this it can be seen that the compressed number answer in Hindu-Arabic notation is 4489. The problem comes from teaching long multiplication in columnar form and only allowing each column to contain one digit. This requires one to handle the carry (or compression of the open number result) in the middle of all the multiplication operations. If one turns the multiplication sum on its side and uses open numbers the process suddenly becomes a lot easier and quicker to perform as one can extend the power of 10 number calculations to handle results with more than one digit. This has the benefit of leaving the compression of the final open number result to the end of the process. Thus the order of operations can be done either right to left (traditional) or left to right (for mental speed maths) provided one is clear about which digit multiplications for each power of ten computation should be added together. For example Units: 7x7 = 49 Tens: 6x7+7x6 = 84 100's: 6x6 = 36 result: [36,84,49] = 4489

@@sharonjuniorchess Thankyou for this effort ! Appreciated!

Yeah exactly! (a+b)² = a² + 2ab + b². I'd rather do it like this though 512² -> (500+12)² = (500)² + 2(500)(12) + (12)² = 250,000 + 12,000 + 144 = 262,144 It's kinda easier to digest. But either way works.

I agree!

Why not, we all love it

@@stevenbrock528 for numbers all 9s you can do 99^2= 10000-199 999^2=1,000,000-1999 9999^2=100,000,000-19999

carry the 1 where though? To the next row?

@@arpanmascarenhas1048 Just remember that each new number goes into the next two positions. With a three-digit number, think of the third digit as overflow. For example, to square 6789: The first row is 36496481, the square of each digit. For the second row, start with 6×7×2=84. Add to that 7×8×2=112, when, with two spaces reserved for this new number, you now have 8512 in this row. Then add 8×9×2=144 the same way, making this row 851344. I'll add a zero to the end to make the numbers align more clearly, making the second row 8513440. The third row starts with 6×8×2=96. Then add 7×9×2=126, giving 9726. Add two zeroes for alignment, making this row 972600. For the fourth row, you have 6×9×2=108 plus three zeroes for alignment, giving 108000. Adding them up, you get 36496481 + 8513440 + 972600 + 108000 = 46090521, and you're done.

@@zanti4132 Wow ok this was very helpful.. Thank you! Can I reach out to you on instagram?

I dobt get it please help! With graphic

hey i did try the way you mentioned but i am unable to get the right answer if you are available to reply back. please do

Hehe 54

47 years ago for me my how the time has flown, just amazed at how old I have gotten, it was just yesterday I was learning this in math class LOL

Had to look at this and figure it out...it gets sloppy. You put the two numbers together but add the one's digit from 162 to the hundred's digit of 144 together getting 16344 and like standard math this goes below the first number shifting one to the left (leaving a space under the 1's digit) the other 144 in the third row is once again shifted another row leaving an empty space under the 10's digit. It might be easier to figure out than the standard squaring method, but I don't think I could do this in 5 seconds in my head.

Can you please explain this on paper 📜

You use (1000-2)² instead of the (a+b)²
