Greater than sign (>) and less than sign (

1, greater than sign (>) indicates that the number on the left is greater than the number on the right. Such as 2 >; 1 means that the number 2 is greater than the number 1.

2. Less than sign (

3. The greater-than sign and the less-than sign are strict when they are relatively large, excluding the situation of equality. If you want to express a relationship that contains an equation, you can use a sign greater than or equal to (≥) or a sign less than or equal to (≤).

4. The greater than sign and the less than sign are also specially indicated on the number axis. The greater than sign (>) is located on the right side of the number axis, and the less than sign (

In short, the greater than sign (>) is used to indicate that the number on the left is greater than the number on the right and less than the sign (

Greater than sign (>) and less than sign (

The greater than sign (>) first appeared in the works of Italian mathematician Giorgio Tagliacozzi in the 6th century A.D./Kloc-0. He used this symbol to mean "increase" or "exceed".

And the less than sign (

At that time, he used a symbol similar to "V" to express the concept of "lack" or "less", and later this symbol evolved into the present less than symbol.

These symbols have gradually been widely accepted and used in the later development of mathematics, and become the common expressions of comparative size in mathematics. Their forms are fixed and widely accepted and used in different languages and cultures.
