🧠 What is Addition?
Addition means putting things together to find the total.
We use the plus sign (+) and equal sign (=) for addition.
For Example:
🍎 + 🍎 = 🍎🍎 → 1 + 1 = 2
🧮 Addition without Carrying (Single & Double Digit)
👉 Add the numbers column by column.
🟦 Table 1: Without Carrying
| Number 1 | + | Number 2 | = | Answer |
|---|---|---|---|---|
| 2 | + | 3 | = | 5 |
| 5 | + | 4 | = | 9 |
| 11 | + | 6 | = | 17 |
| 21 | + | 15 | = | 36 |
| 32 | + | 14 | = | 46 |
🧮 Addition with Carrying
👉 When the total in the Ones place is more than 9, we carry 1 to the Tens place.
🟩 Table 2: With Carrying
| Tens | Ones | + | Tens | Ones | = | Carry | Answer |
|---|---|---|---|---|---|---|---|
| 1 | 8 | + | 2 | 7 | = | 1 | 4️⃣5️⃣ |
| 2 | 9 | + | 1 | 6 | = | 1 | 4️⃣5️⃣ |
| 3 | 7 | + | 2 | 8 | = | 1 | 6️⃣5️⃣ |
📝 Remember:
When Ones place > 9,
- Keep ones digit down
- Carry over the tens digit to the next column
