Quick Example

Imagine you have a box of laddoos. If you count them one by one, and you have three full groups of ten laddoos, plus seven extra laddoos, then you have a total of thirty-seven laddoos. That's 30 + 7 = 37.

Worked Example

Step-by-Step

Let's find out what number comes after 36 and before 38.
1. Start counting from 1: 1, 2, 3, ...
2. Continue counting until you reach the 'thirties': ..., 34, 35, 36.
3. The very next number after 36 is found by adding 1 to 36.
4. 36 + 1 = 37.
5. The number that comes after 36 is thirty-seven.
6. To check, the number before 38 is found by subtracting 1 from 38.
7. 38 - 1 = 37.
So, the number is 37.

Why It Matters
