1. **State the problem:** Evaluate the expression $$-12 - (14 + -15 \div 15) \times -9$$.
2. **Recall order of operations:** Parentheses first, then division and multiplication from left to right, and finally addition and subtraction.
3. **Evaluate inside the parentheses:**
$$-15 \div 15 = -1$$
So the expression inside the parentheses becomes:
$$14 + (-1) = 13$$
4. **Rewrite the expression:**
$$-12 - 13 \times -9$$
5. **Multiply:**
$$13 \times -9 = -117$$
6. **Rewrite the expression:**
$$-12 - (-117)$$
7. **Subtracting a negative is adding:**
$$-12 + 117 = 105$$
**Final answer:** $$105$$
