The number before 5 is the whole number that comes immediately before 5 when you count upwards. It is one less than 5. We find it by subtracting 1 from 5.

Simple Example

Quick Example

Imagine you have 5 delicious ladoos. If you eat one ladoo, how many are left? You will have 4 ladoos. So, 4 is the number before 5.

Worked Example

Step-by-Step

Let's find the number before 5 using counting:
1. Start counting from 1: One, Two, Three, Four, Five.
---
2. Look at the number you said just before you said 'Five'.
---
3. The number you said was 'Four'.
---
4. So, the number before 5 is 4.

Alternatively, using subtraction:
1. We want the number before 5.
---
2. This means we need to take away 1 from 5.

3. So, calculate 5 - 1.

4. 5 - 1 equals 4.

Answer: The number before 5 is 4.

Why It Matters

Understanding 'before' and 'after' numbers is a basic building block for all math. It helps you with counting, addition, and subtraction, which are used everywhere. Engineers use this concept when ordering steps in a process, and even in finance, knowing the 'previous' day's stock price is crucial.
