Calculating five times the number 5

To calculate five times the number 5, you use multiplication, specifically multiplying 5 by 5. Multiplication here means you are taking the value of 5 and combining it five times, which scales the number up proportionally. Think of it as adding 5 five separate times: 5 + 5 + 5 + 5 + 5. Performing the operation 5 * 5 accomplishes this in a single step. The expression 25 captures this calculation, so when you substitute any value for 5, evaluating 5 * 5 will give you five times that original number.
