Answer 1

The expression 45−(8×3+15) simplifies to 6 by first multiplying 8 by 3, then adding 15 to the result, and finally subtracting this sum from 45, according to the order of operations.

Step-by-step explanation:

We need to simplify the expression 45−(8×3+15) step by step by following the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

1. Solve the expression inside the parentheses (8×3+15). Start by doing the multiplication: 8×3 equals 24.
2. Add 15 to 24 which gives us 24+15 equals 39.
3. Now, subtract the result inside the parentheses from 45: 45−39 which equals 6.

Thus, the final answer is 6.
