1, written narrative language: in the compulsory education stage, words are often used to describe and explain mathematical concepts, theorems, formulas, etc. Through written narration, students can understand and express thoughts and thinking processes in mathematics. For example, "two points determine a straight line" and "equilateral triangle" describe mathematical concepts and properties through text narration.

2. Symbolic language: Symbolic language is a common language form in mathematics and is equally important in compulsory education. Symbols are widely used in mathematics to represent concepts, relationships and operations. For example, letters are used to represent numbers, and symbols such as addition, subtraction, multiplication and division are used to represent operations. This language form is concise and clear, which is helpful to express mathematical ideas accurately. The use of symbolic language also cultivates students' mathematical reasoning ability and logical thinking ability.

3. Language of images and tables: Images and tables are widely used in compulsory education mathematics teaching. Graphics and tables are often used in mathematics to describe and explain mathematical concepts, theorems and formulas. Such as drawing function images, displaying geometric figures, making data tables, etc. Such a language form can intuitively show mathematical relations and laws and help students better understand and master mathematical knowledge.
