Re: help me with a simple pre-algebra problem please
In front of a number, a positive and a negative makes a negative, and a negative and a negative makes a positive. Applying this:
-10 - (-8) + (-4) - 20 = -10 + 8 - 4 - 20 = - 26
If you have trouble with this, try drawing a number line to help you picture it
