Sum symbol12/30/2023 ![]() In computer applications (like Excel) the symbols mean not equal. You may also come across other related symbols, although these are less common: It is most commonly used to show the result of a calculation, for example 2 + 2 = 4, or in equations, such as 2 + 3 = 10 − 5. The = equals symbol is used to show that the values on either side of it are the same. 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.− is used when one or more numbers are to be subtracted, for example, 2 − 2. ![]() This symbol has two main uses in mathematics: Our page on Positive and Negative Numbers explains that a number without a sign is considered to be positive, so the plus is not usually necessary. The + symbol can also be used to indicate a positive number although this is less common, for example, +2. The addition symbol + is usually used to indicate that two or more numbers should be added together, for example, 2 + 2.
