🎯 What You'll Learn

You will learn to add hundreds, which is just like adding single digits but with extra zeros!

🏪 Market Story

Tunde's mother gives him ₦200 for transport and ₦300 for food. How much does Tunde have altogether? He thinks: "If 2 + 3 = 5, then ₦200 + ₦300 = ₦500!" Adding hundreds is just like adding small numbers.

📝 Let's Learn

Adding hundreds works the same way as adding ones, just with two extra zeros:

  • 1 + 2 = 3, so ₦100 + ₦200 = ₦300
  • 3 + 4 = 7, so ₦300 + ₦400 = ₦700
  • 5 + 5 = 10, so ₦500 + ₦500 = ₦1,000

Example 1: ₦100 + ₦400 = ₦500. Think: 1 + 4 = 5, so it's 500.

Example 2: ₦200 + ₦600 = ₦800. Think: 2 + 6 = 8, so it's 800.

Example 3: ₦300 + ₦300 = ₦600. Think: double 3 = 6, so it's 600.
