Definition

What is it?

The number 49 is a whole number that comes after 48 and before 50. It is a two-digit number, meaning it has a '4' in the tens place and a '9' in the ones place. We use 49 to count things, measure quantities, and perform calculations.

Simple Example

Quick Example

Imagine your favourite cricket team scored 48 runs in their first 5 overs. If they score 1 more run, their total score will be 49 runs. This is how we count up to 49.

Worked Example

Step-by-Step

Let's say you have a box of laddoos. You count them one by one.
1. You count 1, 2, 3... all the way up to 40 laddoos.
---
2. After 40, you continue counting: 41, 42, 43, 44, 45, 46, 47, 48.
---
3. The very next laddoo you count will be the 49th laddoo.
---
So, if you have 48 laddoos and add 1 more, you get 49 laddoos.

Why It Matters

Understanding numbers like 49 helps you count, compare quantities, and manage money in daily life. It's crucial for careers like being a shopkeeper counting items, a data analyst looking at numbers, or an engineer designing structures that require precise measurements.

Common Mistakes

MISTAKE: Confusing 49 with 94. | CORRECTION: Remember that the first digit (4) tells you how many tens you have, and the second digit (9) tells you how many ones. 49 is 'four tens and nine ones', while 94 is 'nine tens and four ones'.

MISTAKE: Thinking 49 is a single-digit number. | CORRECTION: 49 has two digits (4 and 9), so it's a two-digit number. Single-digit numbers are from 0 to 9.

MISTAKE: Counting 49 as the number before 48. | CORRECTION: Numbers increase as you count. 49 comes AFTER 48, and 48 comes BEFORE 49.
