When you add a positive and negative number, you need to look at the "size" or "magnitude" of the number.

-32 has a magnitude of 32 and is negative.

The answer will be positive, if the positive number has a bigger magnitude.

The answer will be negative, if the negative number has a bigger magnitude.

Subtracting
