Calculating five times the number 27

To calculate five times the number 27, you use multiplication, specifically multiplying 27 by 5. Multiplication here means you are taking the value of 27 and combining it five times, which scales the number up proportionally. Think of it as adding 27 five separate times: 27 + 27 + 27 + 27 + 27. Performing the operation 27 * 5 accomplishes this in a single step. The expression 135 captures this calculation, so when you substitute any value for 27, evaluating 27 * 5 will give you five times that original number.
