First, when riding a bicycle, have you ever thought about how many meters the bicycle has walked with the pedal? We can measure the radius of the wheel, and then use the circumference formula of the circle to find out.

Or lay a rope on the ground to measure, or you have other ways. Then you see the classmate next to you riding faster than you. Have you ever thought about how you judge who is fast and who is slow? Compare distances at the same speed? Or is the same distance faster? Sure, anything will do.

Secondly, because of the primitive nature of mathematics, the development and progress of most disciplines in the world are inseparable from mathematics, which is particularly prominent in the field of architecture and also requires rigorous thinking. Architecture pursues the harmonious unity between man and nature, being born in nature also returns to nature, and realizes the harmonious coexistence between architecture and surrounding environment.

Traditional architecture is the earliest application of mathematical theory, and the most classic is "golden section". For example, the Parthenon in ancient Greece kept its height-width ratio at 0.6 18. Later architects found that the building would be more beautiful if designed according to this ratio.

For the field of modern architecture, applied mathematics is a perfect setting tool, which can avoid unnecessary mistakes to the greatest extent. Architects at all times and all over the world combined architectural knowledge with their own mathematical thinking, which led to all kinds of magnificent buildings we see today.

Third, do you know where you spend the most time on your way to school today? Draw a plane rectangular coordinate system, the abscissa is time, and the ordinate is the distance from home, which is clear at a glance.

Fourth, when you are late, you need to register with the person on duty and ask to write down the name of the grade class. In this way, the school will know which class is the latest this week and which class is the latest. This is also a simple statistical problem.
