Here are the solutions to the problems: a) Calculate 4 + (-3) using a number line Step 1: Rewrite the expression. Adding a negative number is equivalent to subtracting the number. 4 + (-3) = 4 - 3 Step 2: Start at 4 on the number line and move 3 units to the left. 4 - 3 = 1 The answer is 1. b) Calculate 5 + (-7) using a number line Step 1: Rewrite the expression. 5 + (-7) = 5 - 7 Step 2: Start at 5 on the number line and move 7 units to the left. 5 - 7 = -2 The answer is -2. c) Calculate 7 + (-8) using a number line Step 1: Rewrite the expression. 7 + (-8) = 7 - 8 Step 2: Start at 7 on the number line and move 8 units to the left. 7 - 8 = -1 The answer is -1.
