Step-by-step explanation: The answer is positive 3 because if you look on a number line, you will only move 3 spaces to the right. You could also look as this problem as a subtraction problem. 5-2=3. Tip: While adding positive and negative numbers, look at the bigger number in the problem. In this case it's 5. The five is positive so the answer is positive. If the five were to be negative, the answer would be negative. In adding the larger number dictates whether the sum will be positive or negative.
