A math problem is to tell you the known quantity and find out the unknown quantity. The steps to solve mathematical problems need to move the known quantity closer to the position quantity step by step. The more knowledge you have, the easier it will be to solve a math problem. The axiomatic system of the Elements of Geometry is also established in this way: 1, and five postulates (known quantities) are put forward; 2. Prove various theorems (quantities). 3. Deduce the big theorem with the small theorem.
But some problems are very difficult and need a long transformation process to solve. At this time, the theorem plays an important role. Theorem is a big law that summarizes the laws of individual situations and proves them. It can reduce the steps of solving problems and can be directly used to prove mathematical problems without proof. For example, if you want to go to a place, it will take a long time to go around at a low speed, but you can drive at a high speed in one step, and it will be very fast.
The proof of various theorems is the progress of mankind, which lightens people's thinking burden, enables mathematicians to devote more energy to bigger problems, and plays a great role in revealing the laws of the world. The building of mathematics is made up of various theorems. With the foundation in front, we can solve the more difficult problems in the back. These theorems are called knowledge. The more knowledge, the easier it is to solve problems. Knowledge is the second element to solve problems.
