In mathematics, division by two, also called halving, mediation, or dimidiation, is common in formulas and as a step in arithmetical calculations; it is equivalent to multiplication by one half. Starting with an arbitrary number or quantity x {\displaystyle x} , its division by two can be written as any of the following equivalent expressions: x ÷ 2 , x / 2 , x 2 , 1 2 x , 0.5 x .
