1. The problem asks: Which number is 5 units forward from -5? 2. To find a number that is a certain number of units forward on the number line, we add that number of units to the starting number. 3. The starting number is -5, and we want to move 5 units forward, so we calculate: $$-5 + 5$$ 4. Simplifying the expression: $$-5 + 5 = 0$$ 5. Therefore, the number 5 units forward from -5 is 0.
