**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?**

**Add up all the numbers.****Count how many numbers you added.****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.
