The greater than sign, the less than sign and the equal sign are all written in the left half of Tian Zige, aligned up and down, occupying two squares, the upper left square and the lower left square. As shown in the figure below:

Is greater than, which can be expressed as > by mathematical symbols. When one value is greater than another, the greater than sign (>) is used to indicate the relationship between them.

Less than, when one value is less than another value, less than sign (

When one numerical value is equal to another, the equal sign "=" is used. For example: a=3, b=3, A and B are equal, that is, a=b(a equals B).

Other inequality symbols

The symbol ">" and "=" are organically combined to obtain the symbol "≥". When one numerical value is greater than another or two numerical values are equal, the symbol "≥" is used to read "greater than or equal to", sometimes called "not less than". For any two real numbers A and B, their corresponding points A and B can be found on the same axis. If point A is to the right of point B or A and B coincide, then A ≥ B..

Similarly, the symbol "
