In math, the “obelus” is a symbol for what?

• Division:An obelus is a symbol consisting of a short horizontal line with a dot above and below (÷). It is mainly used to represent the mathematical operation of division. It is therefore commonly called the division sign. The symbol represents a fraction with dots in place of the denominator and numerator. The obelus was first used as a symbol for division in 1659 by the Swiss mathematician Johann Rahn in his book Teutsche Algebra It is widely believed that John Pell, who edited the book, is the person responsible for the use of the symbol.
