What does it mean to read according to the operation?
Reading according to the meaning of operation is generally mathematical reading.

In mathematics, formula refers to the formula listed in the calculation of numbers (or algebraic expressions), including numbers (or letters instead of numbers) and operation symbols (four operations, power, root, factorial, permutation and combination, etc. According to different calculation methods, formulas can be divided into horizontal formula, vertical formula and recursive formula.

Unlike expressions, expressions are expressions that connect data of the same type (such as constants, variables, functions, etc.). ) Use operation symbols according to certain rules, and expressions are expressions that connect numbers through operation symbols to calculate results, and need an equal sign.

The function of formula in mathematics;

1 stands for mathematical operation: expressions can represent various mathematical operations, such as addition, subtraction, multiplication, division, exponent, logarithm, etc. Mathematical problems can be transformed into the calculation of symbols and numbers through formulas, so that the solution of the problem can be obtained.

2. Simplify the calculation process: Formulas can simplify the calculation process by using mathematical formulas and theorems. For example, by using the algorithms of distribution law, association law and exchange law, we can simplify complex mathematical expressions into a form that is easier to calculate.

3. Reasoning and proof: In mathematics, formulas can also be used for reasoning and proof. Mathematical problems can be turned into logical reasoning problems by formulas, and the correctness of mathematical theorems and propositions can be proved by algebraic operations.

4. Modeling and problem solving: Formulas can also be used to build mathematical models and solve practical problems. By transforming practical problems into mathematical problems, expressing and solving these problems with formulas, we can get the solutions of practical problems.
