Quick review of all operations:

• Addition (+): Combining amounts. ₦45 + ₦30 = ₦75.
• Subtraction (−): Taking away or finding the difference. ₦100 − ₦65 = ₦35.
• Multiplication (×): Equal groups. 6 × ₦25 = ₦150.
• Division (÷): Sharing equally or grouping. ₦150 ÷ 6 = ₦25.

Mixed Problem 1: Tunde has ₦500. He buys 3 shirts at ₦120 each. How much is left? 3 × ₦120 = ₦360. ₦500 − ₦360 = ₦140.

Mixed Problem 2: Amina and Bola earn ₦180 together and share equally. How much does each get? ₦180 ÷ 2 = ₦90.

Mixed Problem 3: Funke buys 4 oranges (₦10 each) and 6 bananas (₦5 each). Total: (4 × ₦10) + (6 × ₦5) = ₦40 + ₦30 = ₦70.
