Repeated Addition

🎯 What You'll Learn

You will see that multiplication is the same as repeated addition — adding the same number again and again.

🏪 Market Story

Chidi buys 4 sachets of pure water. Each sachet costs ₦20. He could add: ₦20 + ₦20 + ₦20 + ₦20 = ₦80. Or he could multiply: 4 × ₦20 = ₦80. Both give the same answer, but multiplication is faster!

📝 Let's Learn

Repeated addition means adding the same number multiple times. Multiplication is a shortcut for this.

• ₦20 + ₦20 + ₦20 = 3 × ₦20 = ₦60
• ₦10 + ₦10 + ₦10 + ₦10 + ₦10 = 5 × ₦10 = ₦50
• ₦5 + ₦5 + ₦5 + ₦5 = 4 × ₦5 = ₦20

Example 1: 3 + 3 + 3 + 3 + 3 = 5 × 3 = 15.

Example 2: ₦50 + ₦50 + ₦50 = 3 × ₦50 = ₦150.

Example 3: 7 + 7 = 2 × 7 = 14.

✏️ Practice Questions

1. Write as multiplication: ₦10 + ₦10 + ₦10 + ₦10 + ₦10 + ₦10 = ?
2. Write as repeated addition: 4 × 8 = ?
3. Tunde buys 5 meat pies at ₦30 each. Write this as repeated addition AND as multiplication. What is the total?

1. 6 × ₦10 = ₦60.
2. 8 + 8 + 8 + 8 = 32.
3. ₦30 + ₦30 + ₦30 + ₦30 + ₦30 = 5 × ₦30 = ₦150.

💡 Remember

Multiplication is a shortcut for repeated addition. Instead of adding ₦20 four times, just say 4 × ₦20 = ₦80. It saves time!
