Multiplication Math Hack for 2-Digit Numbers Ending in 1 (Mental Math Trick) #shorts #math #maths

Iykyk ...all these tricks are indian Vedic mathematics

It fake i tried it

Wrong
61
x31 = is 127 🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️🤦‍♀️

How about 93x72 to easy?

that's so cool

Does this thing work with other numbers above double digits?

The trick I do is using the multiplication chart lol (unless if the numbers aren’t on the chart then I would probably use this)

1 x 1 = 1 so wha

1891

51x71??? This method doesn’t work all the time

this does not even work properly due to your lack of explanation ...

81
X 31
---------------
24111

according to your "hack" the answer is 24111 because you never explained what to do if the 2 numbers you add together happens to be 10 or greater

this literally just blows my mind. How did you do that whenever I try to check it never works I literally watch a video of 100 million times and I try but it doesn’t work and I don’t know how I don’t do that

I’ve checked the answer on a calculator. Turns out it was wrong.

So basically you just solved the multiplication…

This only works with 2 digit numbers ending with 1

why didnt he add the first digits together and does it mean if it was 2, the answer would have 2 in the ones place..?

Damn that’s crazy. Wow 🤯😯👍

Doesn’t work with 93x27

Just teach the foil method which works for all multiplication

(60 + 1)(30 + 1)=1800+30±60±1

The answer is 92 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😅😅😅😅😅😅😅😅😅😅😅😅😅😮😮😮😮😮😮😮😮😮😮😮😮😮😮😮😅😅😅😅😅😮

This is fake , when I do 81× 71 with your trick it get the answer as 56151, but when I do without trick I gets 5751 dear frnds this is fake don't use this trick in exams

Thank you so much bro😊😊😊😊

If its for eg: 81x91 when u add the 2 numbers it = 17 carry the 1 to the last step number so 72+1 = 73 and the answer is “7371” not “72️⃣71

In that case, would it be faster just to multiply them? It’s just going to screw with people heads all these weird tricks. Who’s gonna remember the 10,000 little tricks if you can just use 1 consistent structured approach … even if it is genius level

Umm what if there is a carry towed

They don’t always work not on every number that ends in one….. I did the same hack with 91× 41 and my answer was 36,131. But with a calculator the answer is 3731.

This I it works because of the 1 in the ones place. Any other number it wouldnt

If you add 1 and one then divide multiply and subtract... then add to the first then divide by 2 then subtract 1 and multiply by 1. Then add by 2 subtract 1 divide by 1 then multiply by 2.... see the answer is so easy!

This is a cool math trick for a single number. Me: if it only works for one or two numbers then how is this cool? I will never get this time back and I feel like this video has wasted a very important time in my life.

Thanks!

these are terrible techniques for maths

Hurga

This was how I was taught to do double digit multiplication.
The order is lasts, innies + outties, then firsts.
Ex: 61×31,
Step 1. Lasts, 1×1 = 1
Step 2. Innies + outties, 3×1 + 6×1 = 9
Step 3. Firsts, 6×3 = 18
Step 4. Figuring out where the numbers go, 1,9,18, the 1 goes last, the 9 goes next to the 1(any number over 10 you carry the tens digit to the next number in the sequence,) the 18 goes first so the answer is 1891.
While yes this one is easy this sequence works for all 2 digit by 2 digit multiplication and can be adapted for 3 digit multiplication as well.
Ex2: 78×34
8×4 = 32
8×3 = 24. 7×4 = 28. 24+28 = 52
7×3 = 21
32 is first so the 2 is the ones digit, carry the 3. 52 is next, add the 3 from before to get 55. So 5 is the tens digit, carry a 5. 21 is last add the 5 to get 26, so a 6 is the hundreds digit the 2 is alone so no need to carry and it becomes the thousands digit.
So 78×34 = 2652.

I want to see how many people can get this one right.
85×47.

If you want more math tips I know a few.

Just do 92.1112(483) z

Any two digit number ? How about 69mutiply 69 …try it. Pls

😂😂😂😂😂

stupid don't spread half or fake knowledge what if you do 54×21

But let's do like 25 times 40 u do the first 0 times 5 which is 0 then the 2 plus 4 which is 6 the 2 times 4 which is 8 so together it is 860??????

ok show the proof

Thank you bro that make me past on math test for that i will subscribe you

What- I thought everyone knew that😮

Thank u

tysm!

W explanation

81x21

Are you seriously right meow bro

Fack 😂😅with other problems that ends with 1

bro just do it normally

Guys these brain dead babies in the comment section don’t know how to correctly use it but it always works all long as the 1 St digit is 1
