Answer 2

You're suppost to find what your awnser is.

Answer 3

That's the question.

Answer 4

i am supposed to make u understand how to solve it, you are supposed to actually solve it....

Answer 5

I would like to understand.

Answer 6

great!
so u know what absolute value means ? |...|
what is |-4|=?
