4x4 + 4x4 + 4 - 4x4

16 + 16 +4 - 16
32 +4 -16

36- 16 = 20

lol u guys are wrong. that's why 73% ppl get this wrong.
I always get good grades in math.
4x4+4x4+4-4x4=?
there are 3 x4's. it means 4 cubed=64
the rest are addition and subtraction :
4+4+4-4=8
add them all :
64+8=72

it's 72

Wolfram says 20 too.

I feel stupid.I forgot the subtraction.I'm a disgrace to my asian family :c

What? I believe you belong to 73%, not us.

A2+A2+A-A2=A2+A
A2+A2-A2=A2+A-A
A2=A2

Here I mathematically proved why it is 20. Something kids learn in Russia at age 11. I also doubt that 73% of people are that stupid.

320

He might.

Here is another Math problem:
9 balls. They all have the same shape, color, etc. The only difference is that one of the balls is a little bit heavier than the rest, by so little, that you can't even tell. The rest 8 are equal. You have a classic scales like the ones in the picture. You can only use the scales twice to figure out which ball is heavier. Go ahead.
