The greater than sign is the symbol of inequality operation in mathematics. The greater than sign is widely used in arithmetic, which is a necessary content for primary schools. In 1655, Wallis is used to mean "equal to or greater than", and in 1670, he also means "equal to or greater than" and "equal to or less than" respectively.

Development history

163 1 year, the Englishman Riholt began to adopt the symbols of "greater than" and "less than".

Poincare and Borel introduced the symbols << (far less than) and >> (far greater than), which were quickly accepted by the mathematical community and are still in use today.
