2x2=?
100-2=98
98+98=196
98x98=9,604
2x2=1,969,604

funny thing:
a) 50 x 50 =?
b) 100-50=50 and 100-50=50
c) so. 50+50=100, and a = 100_
d) _ = 50 x 50? aaaaaaaand we back to a!

This is just stupid and a completely useless way to solve multiplication problems.

1) just about everyone here has access to calculators which can literally determine the answer in seconds
2) assuming you had ANY sort of education in elementary school arithmetic, doing multiplication of large numbers should not be too difficult.
3) try solving a problem like 47 x 66 with this method and tell me it's quicker to solve it that way
4) pic related: method I learned in school

because maths isn't about doing sums

The image works of the following method.
97*96<=>(100-(100-97))*(100-(100-96))<=>(100-3)*(100-4)=100*100-100*4-3*100+3*4
This last bit can be shortened to: 100*(100-3-4)+3*4
The underscored part is the red part of the image and the non-underscored part is the blue part of the image.
This method can be used for any two numbers, but as shown in other comments it's not effective unless it's a high two ciphered number. In my opinion this method is a mere curiosity.

I think this works only with 90-something numbers.

I tried this out with 45 x 75. I got 201375 when really its 3375.

45 x 75 = 20 1375
I I I I
55 + 25 -> 80 I

I am pretty sure 86*80 does not equal 66280 (14+20=34 100-34=66, 14*20=280)

thank you tuban math man

learning more math on tumblr than in school???

sounds more like a personal problem than one with the system

they dont say anything about the system, but its flawed
not saying the education system isnt ******

well if you have like 47*68 you'll get that 100-47=53 and 100-68 is 32. you'll add them together to make the sum 85. now you just have to solve the simple multiplication 53*32 in your head, or repeat this process.

this thing is only smart if the number you have to multiply are close to 100 or 0 so you can do the multiplication in your head

now do 56*72, see as difficult as the starting problem
this trick works only works well for both numbers close to 100,1000...
so not that useful
better is to do 50*70+6*70+50*2+6*2

proof of this trick
c*d=e
100-c=a and 100-d=b
than
(100-a)(100-b)=10000-100a-100b+ab=100(100-(a+b))+ab=e
