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

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.
