Mathematics often passes people by, and people can't live without it. It has made great contributions to people's lives. Mathematics is often used in our class. For example, the class charges for meals, and there are 62 students in one class.

There are 60 students who eat at school, and 85 yuan each can cope. In this case, we must work out how much 60 people should pay. The result can be easily calculated by multiplication. Just use 85x60= 60 people in the class pay a few dollars. This is the most common example around us.

In our life, it is also closely related to mathematics. Everyone goes to the supermarket once a week, but generally only takes 50 yuan -80 yuan. At this time, we will buy things in a planned way.

But the price of goods is often not an integer, such as a bar of soap 5.60 yuan, a pair of cloth shoes 12.70 yuan. At this time, you should have good oral expression skills. You can't take your calculator to the supermarket every time. Therefore, if you want to buy, you must think about buying well, or you will not have enough money.

If you grow up to be a designer, you should make clear the length and width of each brick! Even the error of 0. 1 cannot exist!

This shows how important mathematics is! Therefore, we should learn math well now and build our motherland when we grow up!
