is used in spreadsheets and other computer applications. ÷ is used commonly in handwritten calculations and on calculators, for example, 2 ÷ 2.

These symbols are both used to mean division in mathematics. For example, if you see a number written outside brackets with no operator (symbol or sign), then it should be multiplied by the contents of the brackets: 2(3+2) is the same as 2×(3+2). Less commonly, multiplication may also be symbolised by a dot. The symbol * is used in spreadsheets and other computer applications to indicate a multiplication, although * does have other more complex meanings in mathematics. These symbols have the same meaning commonly × is used to mean multiplication when handwritten or used on a calculator 2 × 2, for example.

The − symbol is also commonly used to show a minus or negative number, such as −2.
