Calculating five times the number 55

To calculate five times the number 55, you use multiplication, specifically multiplying 55 by 5. Multiplication here means you are taking the value of 55 and combining it five times, which scales the number up proportionally. Think of it as adding 55 five separate times: 55 + 55 + 55 + 55 + 55. Performing the operation 55 * 5 accomplishes this in a single step.
