Five Times The Difference Of A Number And 3

When it comes to mathematical expressions, understanding how to calculate the five times the difference of a number and 3 can be a valuable skill. By following a few simple steps, you can easily solve this type of problem and gain a deeper understanding of algebraic concepts.

What Does “Five Times The Difference Of A Number And 3” Mean?

Before we delve into the calculations, let’s break down the meaning of the expression “five times the difference of a number and 3.” In mathematical terms, the difference between two numbers is obtained by subtracting one number from another. In this case, we are looking at the difference between a number and 3.

To find the difference between a number (let’s call it x) and 3, we would calculate x – 3. Multiplying this difference by five gives us the final expression: 5(x – 3).

Steps to Calculate Five Times The Difference Of A Number And 3

Now that we understand the concept behind the expression, let’s walk through the steps to calculate five times the difference of a number and 3:

  1. Identify the number: Let’s say the number we are considering is x.
  2. Subtract 3 from the number: Calculate x – 3 to find the difference between the number and 3.
  3. Multiply the difference by five: Multiply the result from step 2 by 5 to get the final answer.

Example:

Let’s use an example to illustrate the calculation. If the number we are considering is 7, we would follow these steps:

  1. Identify the number: x = 7
  2. Find the difference: 7 – 3 = 4
  3. Multiply the difference by five: 5 * 4 = 20

Therefore, five times the difference of 7 and 3 is 20.
