Calculating five times the number 40

To calculate five times the number 40, you use multiplication, specifically multiplying 40 by 5. Multiplication here means you are taking the value of 40 and combining it five times, which scales the number up proportionally. Think of it as adding 40 five separate times: 40 + 40 + 40 + 40 + 40. Performing the operation 40 * 5 accomplishes this in a single step. The expression 200 captures this calculation, so when you substitute any value for 40, evaluating 40 * 5 will give you five times that original number.
