Math is very useful. It can help you do many important things. Then     1     can you use math in your everyday life? Let me give you some examples. First of all, you’ll learn in math class how to calculate (计算) interest. You can use the skill to manage your money.

Geometry (几何学) and trigonometry (三角学) can help you do better     2     sports. It can help you work out the best way to hit a ball or run around a track.

Calculating areas is another important math skill. People use math skills when     3     cook. For example, you can use proportions (比例) to make the correct calculations for each ingredient. You’ll use math when you go shopping. Stores often have sales. You’ll also use math to decide which kind of soda     4     the best deal.

Some children tell me they hate math. They think math is useless and that the only reason to learn it is to pass exams. I hope they’ll learn more about how people     5     math every day. Once they see how math can be used, I think they’ll view it as important and become more interested in the subject.
