British mathematician Thomas Harriot proposed and used the greater than sign and the less than sign for the first time. Thomas Harriot is a famous British astronomer, mathematician and translator.
He used the symbol greater than ""for the first time in Usage Analysis, but it was not published until 163 1 year after his death. Therefore, it is generally considered that the greater than sign and the less than sign are used only in 163 1 year. But it was not accepted by mathematics at that time, and it was not until more than one hundred years later that it gradually became a standard application symbol.

The mathematical symbol greater than or equal to is ≥. When one value is greater than another value or two numbers are equal, the symbol ≥ is used, which is also 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..
