Adding Three Prices at the Market

🎯 What You'll Learn

You will practise adding three two-digit prices together, just like shopping at a real market.

🏪 Market Story

Amina is buying ingredients for jollof rice. She needs tomatoes (₦25), rice (₦40), and oil (₦15). She needs to know the total before she pays. She adds step by step: ₦25 + ₦40 = ₦65, then ₦65 + ₦15 = ₦80. She needs ₦80 for all three items.

📝 Let's Learn

When adding three bigger numbers, add two of them first, then add the third.

Tip: Add the easiest pair first. Round numbers (like ₦40) are easiest to add.

Example 1: ₦20 + ₦35 + ₦10. Start with ₦20 + ₦10 = ₦30 (easy!). Then ₦30 + ₦35 = ₦65.

Example 2: ₦15 + ₦22 + ₦13. Add: ₦15 + ₦22 = ₦37. Then ₦37 + ₦13 = ₦50.

Example 3: ₦30 + ₦25 + ₦30. Add: ₦30 + ₦30 = ₦60. Then ₦60 + ₦25 = ₦85.

✏️ Practice Questions

1. Tunde buys biscuits for ₦15, juice for ₦20, and bread for ₦25. What is the total?
2. ₦30 + ₦18 + ₦12 = ?
3. Funke buys an exercise book (₦35), a pen (₦20), and a ruler (₦10). How much does she spend?

1. ₦15 + ₦20 + ₦25 = ₦60. (₦15 + ₦25 = ₦40, then ₦40 + ₦20 = ₦60.)
2. ₦30 + ₦18 + ₦12 = ₦60. (₦18 + ₦12 = ₦30, then ₦30 + ₦30 = ₦60.)
3. ₦35 + ₦20 + ₦10 = ₦65. (₦20 + ₦10 = ₦30, then ₦30 + ₦35 = ₦65.)

💡 Remember

When adding three prices, find the easiest pair to add first. Look for numbers that make a round ten. Then add the third number to the result.
