The symbol of inequality is a symbol used to express the unequal relationship between two quantities. At present, there are five commonly used inequality symbols: "≦" (inequality symbol) and ">" (greater than sign).
Generally, pure greater than sign ">" and less than sign "are used.
There are sizes of quantities, and there are equal or unequal relations when there are sizes. Equality relations can be studied by equations, and inequality relations need special mathematical tools to study, which is inequality.
Chapter 9 "Inequalities and Inequality Groups" of Mathematics published by People's Education Press (the second volume of Grade 7) has studied the properties of inequalities, one-dimensional linear inequalities and their applications. While learning this knowledge, we come into contact with a new mathematical symbol-inequality symbol, which is the symbol used to express inequality relations. There are five commonly used inequality symbols: "8800;" (inequality sign) and ">" (greater than sign), "
The equal sign is just a member of the big family of mathematical symbols. There are hundreds of mathematical symbols used in middle schools, and each symbol has a short story. If you are interested, you may wish to check the information and understand their context, and you will find that the creation of mathematical symbols also flashes the whimsy of mathematicians.
Mathematical symbol No.1 provides favorable conditions for the development of mathematics, which makes the expression of mathematical content simple and convenient, thus improving the calculation efficiency in mainland China and promoting in-depth research.
