What does arithmetic mean?

Think of your test scores. Sometimes you get a high score, sometimes a low one. You calculate your average score to get a general idea of how you performed.

It’s a simple way to find a “middle” value for a set of numbers.

How do I calculate it?

  1. Add up all the numbers.
  2. Count how many numbers you added.
  3. Divide the total by the count.

Example:

Imagine you got these marks in your tests: 75, 80, 92, and 85.

  • Add the scores: 75 + 80 + 92 + 85 = 332
  • Count the number of tests: 4
  • Divide the total by the count: 332 / 4 = 83

So, your average score (Arithmetic Mean) is 83!

Why is it Important?

  • It helps you understand your overall performance.
  • Used in many areas like economics, statistics, and daily life.
