What's (negative 7) plus (positive 7) plus (negative 17) (adding positive and negative numbers)

The answer is -17

The negative 7 and positive 7 add up to 0. They are opposites which cancel out. Think of it like being 7 dollars in debt (negative 7) and that debt is fully canceled out by the positive amount of money (positive 7). Put another way, the negative 7 means you go down 7 while the positive 7 means you go up 7.

After the first two terms cancel to 0, the -17 is the only thing left. Adding 0 to any number keeps that number the same.
