🏪 Market Story

Bola has ₦20 in her pocket. Her grandmother gives her ₦15 more for being a good girl. "How much do I have now?" Bola wonders. She thinks: ₦20 + ₦15. The tens: 20 + 10 = 30. The ones: 0 + 5 = 5. Total: ₦30 + ₦5 = ₦35!

📝 Let's Learn

To add amounts up to ₦50, you can add the tens first, then add the ones.

Example 1: ₦12 + ₦15. Tens: 10 + 10 = 20. Ones: 2 + 5 = 7. Total: ₦27.

Example 2: ₦30 + ₦20. Tens: 30 + 20 = 50. Ones: 0 + 0 = 0. Total: ₦50.

Example 3: ₦24 + ₦13. Tens: 20 + 10 = 30. Ones: 4 + 3 = 7. Total: ₦37.

This method is called partitioning — you split numbers into tens and ones, add each part, then put them back together.
