Compare the numerical expressions 9 × (15 – 8) and 15 – 8. What strategy or tool would you use to solve the problem, and what is the answer?

• Use the order of operations to evaluate both expressions; 9 × (15 – 8) = 63 and 15 – 8 = 7.

• Estimate both expressions; 9 × (15 – 8) = 135 and 15 – 8 = 23.

• Use a calculator to find 9 × (15 – 8) = 17 and 15 – 8 = 3.

• Add the numbers in each expression; 9 × (15 – 8) = 23 and 15 – 8 = 13.
