1. **Stating the problem:** We need to evaluate the expression where the plus sign between -9 and -3 is actually a division sign, so the expression is $$-9 \div -3$$. 2. **Formula and rules:** Division of two numbers is performed by dividing the numerator by the denominator. Important rule: Dividing two negative numbers results in a positive number. 3. **Intermediate work:** $$-9 \div -3 = \frac{-9}{-3}$$ We can cancel the negative signs: $$\frac{\cancel{-9}}{\cancel{-3}} = \frac{9}{3}$$ 4. **Simplification:** $$\frac{9}{3} = 3$$ 5. **Final answer:** The value of $$-9 \div -3$$ is **3**.
