## Topic 22: Approximation

These questions are good common sense practical maths.

When you are working out real-life maths problems, you don't always have to use exact values - approximate values will do.

A good example is working out the total cost of several items in a shop.

£3.49 is approximately £3.50

£2.98 is approximately £3.00

£3.50 + £3.00 = £6.50

This is a much easier calculation to do that £3.49 + £2.98, and gives a useful approximate total (useful for working out if you have enough money to buy the two items, or how much change you should get).
