Calculating five times the number 13

To calculate five times the number 13, you use multiplication, specifically multiplying 13 by 5. Multiplication here means you are taking the value of 13 and combining it five times, which scales the number up proportionally. Think of it as adding 13 five separate times: 13 + 13 + 13 + 13 + 13. Performing the operation 13 * 5 accomplishes this in a single step. The expression 65 captures this calculation, so when you substitute any value for 13, evaluating 13 * 5 will give you five times that original number.
