Thanks but I still don't understand...what if when add two negative, nonzero integers? still "maybe be positive or negative"?

Two negative integers will also add up to a negative sum.
Study the website I posted. 
I am going to practice more from the link, thank you Ms.Sue :)

You're welcome, Lauren.
