The Deep Dive
Sure! The expression \( -5 - (-7) \) can be simplified by recognizing that subtracting a negative number is the same as adding its positive counterpart. So this becomes \( -5 + 7 \). When you add those numbers together, you get \( 2 \). If you're ever confused with negatives, a neat trick is to visualize a number line! Moving left represents subtraction, and moving right represents addition. When you subtract a negative, you're actually moving to the right, which is like gaining positive ground!
