if you have -1 plus 2 plus 3 plus -2 what do you get and how

Hi there!

-1 + 2 + 3 + -2 = 2

Lets take this slow. 

First, -1+ 2 = 1

Second, 3 + -2 = 1

If you add the answers from the first and second, you get 2.

Basically, you paired off the numbers.

(-1+2) + (3+-2)

Solve each problem in the parentheses first, then add them together. Hope this helped!
