Calculating five times the number 38

To calculate five times the number 38, you use multiplication, specifically multiplying 38 by 5. Multiplication here means you are taking the value of 38 and combining it five times, which scales the number up proportionally. Think of it as adding 38 five separate times: 38 + 38 + 38 + 38 + 38. Performing the operation 38 * 5 accomplishes this in a single step. The expression 190 captures this calculation, so when you substitute any value for 38, evaluating 38 * 5 will give you five times that original number.
