To verify the equation \( a - (-b) = a + b \) for the given values of \( a \) and \( b \), we will calculate both sides of the equation for each pair of values and check if they are equal. ### Step-by-Step Solution: 1. **For (i) \( a = 21, b = 18 \)**: - **Left Hand Side (LHS)**: \[ a - (-b) = 21 - (-18) = 21 + 18 = 39 ...
