1, definition and symbol
Greater than or equal to means that one value is greater than or equal to another value. Symbolized as "> =", a horizontal line is added between two values to indicate the relationship between them. For example, a is greater than or equal to b, which means a >；; = B. Less than means that one value is less than another. Symbolized as "
2. Numerical comparison
The symbols greater than or equal to and less than are used to compare the sizes of two numerical values. When two numerical values are equal, a sign greater than or equal to can be used. For example, a equals b, which can be expressed as a >；; = B. When one value is greater than another, the greater than sign can be used.
For example, a is greater than b, which can be expressed as a >；; B similarly, when one value is less than another value, the less than sign can be used. For example, if a is less than b, it can be expressed as a.
Unequal relation and its mathematical application;
1, inequality relation
Symbols greater than or equal to and less than can also be used to represent inequality relations. When one value is not equal to another, you can use the greater than sign or the less than sign. For example, a is not equal to b, which can be expressed as a >；; Or a < B. The expression of this inequality relationship can be used for problems such as inequalities or equations in mathematics.
2. Mathematical application
Symbols greater than or equal to and less than are widely used in mathematics to compare the relationship between sizes. They have important applications in algebra, geometry, probability, statistics and other fields. In algebra, symbols greater than or equal to and less than are used to compare the sizes of expressions such as polynomials, equations and inequalities.
In geometry, they are used to compare angles, line segments, areas and other geometric quantities. In probability and statistics, symbols greater than or equal to and less than are used to compare the sizes of probability, samples, statistics, etc.
