1, euler theorem

Euler theorem is a theorem involving graph theory, which was put forward by the British mathematician Euler in the18th century. It defines a connected trace-space-branch acyclic graph, so that the same side will not have the same color. Euler theorem is one of the important formulas in mathematics.

It is called the overpass in mathematics, which lays a solid foundation for mathematics and provides a theoretical basis for many mathematical studies. The cube of any positive integer can be written as the sum of odd and even numbers.

2. Pythagorean theorem

Pythagorean theorem is one of the important mathematical theorems discovered and proved by human beings in the early days, and it is also one of the theorems with the most proof methods. It uses algebraic ideas to solve geometric problems, and it is one of the ties of the combination of numbers and shapes.

Pythagorean theorem occupies a fundamental position in plane geometry, is an important basis for solving triangles, and has universal application in real life. The discovery of Pythagorean theorem is widely used in mathematics and human practice.

3. Fermat Theorem

Fermat's Last Theorem is a special mathematical theorem, which points out that if P is a prime number deficit, then P- 1 ≡ 1 (MODP), then P can be expressed as a 2+B 2. This theorem was first put forward by Fermat, an ancient Greek mathematician, and was finally proved by andrew wiles in 1994 through the efforts of many mathematicians.

4. Murphy's Law

Murphy's law is a psychological effect, pointing out the possibility that everything will go bad, no matter how small it is. It was put forward by eddie murphy, also known as Murphy's theorem. Murphy's law means that if things are likely to go bad, no matter how unlikely it is, it will always happen.

This law tells us that if it is possible to make mistakes, we will make them. Murphy's law is widely used, whether in life or at work, as long as we are prepared, it is possible to avoid some unnecessary troubles.
