Let's imagine you're shopping for your birthday party with your parent. Here's how maths helps you: Example 1: Adding up prices- You want to buy 3 cupcakes that cost £2.50 each
- To find the total cost, you add: £2.50 + £2.50 + £2.50 = £7.50
- You can also multiply: 3 × £2.50 = £7.50
- Your parent has given you £10 to spend
- You've added up your items and they cost £7.50
- £10 - £7.50 = £2.50 left over
- You have enough money and even a bit left!
- You're buying a £20 toy
- Delivery costs £3.50
- Total cost = £20 + £3.50 = £23.50
