1. The problem is to evaluate the expression $10 \times -15^2$. 2. According to the order of operations (PEMDAS/BODMAS), exponents are evaluated before multiplication. 3. First, calculate the square of 15: $$15^2 = 225$$ 4. The expression becomes: $$10 \times -225$$ 5. Multiply 10 by -225: $$10 \times -225 = -2250$$ 6. Therefore, the final answer is $$-2250$$.
