Calculating five times the number 300

To calculate five times the number 300, you use multiplication, specifically multiplying 300 by 5. Multiplication here means you are taking the value of 300 and combining it five times, which scales the number up proportionally. Think of it as adding 300 five separate times: 300 + 300 + 300 + 300 + 300. Performing the operation 300 * 5 accomplishes this in a single step. The expression 1500 captures this calculation, so when you substitute any value for 300, evaluating 300 * 5 will give you five times that original number.
