Simple Example

Imagine you have collected 47 cricket stickers. This means you have forty-seven individual stickers. If you get one more sticker, you will have forty-eight.

Worked Example

Step-by-Step

Let's say you are counting money. You have 4 ten-rupee notes and 7 one-rupee coins.
---
Step 1: Count the value of the ten-rupee notes. 4 notes x 10 rupees/note = 40 rupees.
---
Step 2: Count the value of the one-rupee coins. 7 coins x 1 rupee/coin = 7 rupees.
---
Step 3: Add the values together. 40 rupees + 7 rupees = 47 rupees.
---
So, you have a total of Forty-Seven rupees.

Why It Matters

Understanding numbers like forty-seven is basic for everyday life and for all higher math. It's crucial for managing money, understanding data, and even for careers like engineering, finance, or even running a small business like a chai stall.

Common Mistakes

MISTAKE: Writing '407' instead of '47' when hearing 'forty-seven' | CORRECTION: Remember 'forty' means 4 tens, and 'seven' means 7 ones. So it's 4 tens and 7 ones, which is 47, not 400 and 7.

MISTAKE: Confusing the order of digits, writing '74' instead of '47' | CORRECTION: The 'forty' part comes first, meaning 4 tens, so the 4 is in the tens place. The 'seven' part comes second, meaning 7 ones, so the 7 is in the ones place.

MISTAKE: Thinking forty-seven is a single digit number | CORRECTION: Forty-seven is a two-digit number. Single-digit numbers are from 0 to 9.
