First of all, arithmetic is one of the most basic parts of mathematics. Covers basic operations such as addition, subtraction, multiplication and division. These operation rules are the basis of calculation in our daily life, and they are also the key for us to understand more complex mathematical concepts.
Secondly, algebra is also an important part of mathematics. In algebra, we study the relationship between numbers and symbols. This includes understanding how to operate and solve equations and inequalities with variables, and how to use algebraic expressions to describe and solve practical problems.
Finally, geometry is another basic part of mathematics. Geometry mainly studies the properties of shape and space. Including understanding the basic elements such as point, line, surface and body, and how to use these elements to describe and solve various geometric problems.
Generally speaking, the basic knowledge of mathematics includes arithmetic, algebra and geometry. These basic knowledge have laid a solid foundation for us to understand and master more advanced mathematical concepts.
