Division symbol, mathematical symbol, is a symbol composed of a short horizontal line and two points on both sides of the horizontal line, which is mainly used to represent division operation in mathematics. Division can be applied to many fields such as mathematics, physics and chemistry.

Historical origin

1544, German mathematician Steefel used one or a pair of brackets as the symbol of division in his Integral Arithmetic, such as 8)24 or 8)24 (indicating 24 ÷ 8; Oughtred uses a)b(c) to represent b÷a = c；; J. Mahon (170 1 year) is expressed by d) a+b-c (a+b-c) ÷ d.

In 1545, Stiefel changed the capital German letter D to stand for division. Later, Steven also adopted this symbol, while Gorimad (175 1) used inverted letters to indicate division, such as 12 4=3 and a2b2a2. In addition, in "Principles of Mathematics" published by 1790, division is represented by flat lowercase letters.
