Subtraction of Numbers — Lesson
🌟 Let's Learn Subtraction with a Fun Story! 🌟
Once upon a time in a colorful Indian village, Raju had 10 juicy mangoes 🥭. He gave 3 mangoes to his friends during a picnic. Can you help Raju find out how many mangoes he has left? 🤔
What is Subtraction? ➖
Subtraction means taking away some things from a group. It tells us how many are left after some are taken out.
In Raju's story:
Total mangoes = 10
Mangoes given away = 3
Mangoes left = ?
How to Subtract Numbers? 🧮
| Step | What to Do | Example |
|---|---|---|
| 1 | Write the bigger number first (the total). | 10 |
| 2 | Write the smaller number below it (what you take away). | 3 |
| 3 | Subtract the smaller number from the bigger number. | 10 - 3 = 7 |
So, Raju has 7 mangoes 🥭 left!
Subtraction Table Example
| 10 - 1 | 10 - 2 | 10 - 3 | 10 - 4 | 10 - 5 |
|---|---|---|---|---|
| 9 | 8 | 7 | 6 | 5 |
- Always subtract the smaller number from the bigger number.
- Start subtracting from the right (ones place).
- If you cannot subtract, borrow from the next digit (we will learn this soon!).
The word "subtraction" comes from the Latin word "subtrahere", which means "to pull away." Just like Raju pulled away mangoes from his basket!
- Always check which number is bigger before subtracting.
- Write numbers properly in columns (ones under ones, tens under tens).
- Don’t forget to borrow if needed (for bigger numbers).
- Practice subtraction with everyday things like fruits, toys, or rupees! ₹
- Board exams often ask simple subtraction sums or word problems like Raju’s mangoes.
