Calculating five times the number 54

To calculate five times the number 54, you use multiplication, specifically multiplying 54 by 5. Multiplication here means you are taking the value of 54 and combining it five times, which scales the number up proportionally. Think of it as adding 54 five separate times: 54 + 54 + 54 + 54 + 54.
