Question: Suppose you want to subtract: $-3 - (-6)$. Re-write this subtraction as an ADDITION of signed numbers. $-3 - (-6) = $ Now actually compute $-3 - (-6) = $

1. **State the problem:** We need to subtract $-3 - (-6)$. This means subtracting a negative number from another negative number. 2. **Rewrite subtraction as addition:** Recall the rule that subtracting a negative number is the same as adding its positive counterpart. So, $$-3 - (-6) = -3 + 6$$ 3. **Compute the addition:** Now add $-3$ and $6$. $$-3 + 6 = 3$$ 4. **Final answer:** Therefore, $$-3 - (-6) = 3$$ This shows that subtracting a negative number increases the value.
