1. In math class, the teacher asked us to solve a problem: a building is 59 meters high, the first floor is 4.6 meters high, and the other floors are 3.2 meters high. How many floors does this building have? I think: this is the same as calculating the endpoint with a line segment diagram. Subtract the height of one floor by 4.6 from the total height of 59, divide it by the height of other floors by 3.2, and finally add the number 17 to the first floor and 1 to get18m.
So, I raised my hand and told my teacher what I thought. The teacher said, "No, this is not the same as calculating the end point. There are'18 floors, but only 17 floors can actually live in. "I suddenly realized: I'm trapped! It seems that you still have to hone yourself to find the trap!
2. One day, my father asked me, "There is a parallelogram paper with a base of 10 cm and a height of 4 cm. If you want to cut a square with a side length of 4 cm in the middle, how many centimeters are left? "
I thought about it and said, "Well, 24 centimeters?" Dad said, "That's right! You are great! " It turns out that mathematics is not needed all the time in life. Learning math well means learning everything well. So it is very important to learn math well, and of course other subjects can't be ignored!
Advantages of learning mathematics
People who are good at math are relatively smart and savvy, and they can show their advantages in dealing with people. The faster you think, the more ways and ideas you have. Mathematics is the foundation of other disciplines, and it is easier for people who learn mathematics well to get into other disciplines. Learning software, computer, finance and other engineering majors is even more handy.
It is used everywhere in life. Nowadays, the society is an information society, and mathematical knowledge is used in financial management and computers. Mathematics can cultivate people's integrity and honesty. Mathematics pays the most attention to convincing people by reasoning, and only believes in the results of logical reasoning. Mathematics can cultivate people's tenacity and courage. Mathematics can cultivate people's overall consciousness. Mathematics can cultivate people's good character.
