1. **State the problem:** Evaluate the expression $$-12 \div (-3) - (-6)$$. 2. **Recall the order of operations:** Division and subtraction are performed from left to right. 3. **Evaluate the division first:** $$-12 \div (-3) = 4$$ because dividing two negative numbers gives a positive result. 4. **Rewrite the expression:** $$4 - (-6)$$. 5. **Subtracting a negative number is the same as adding its positive:** $$4 - (-6) = 4 + 6$$. 6. **Calculate the sum:** $$4 + 6 = 10$$. **Final answer:** $$10$$.
