The addition symbol + is usually used to indicate that two or more numbers should be added together, for example, 2 + 2. The + symbol can also be used to indicate a positive number although this is less common, for example, +2. Our page on Positive and Negative Numbersexplains that a number without a sign is considered to be positive, so the plus i...
This symbol has two main uses in mathematics: 1. − is used when one or more numbers are to be subtracted, for example, 2 − 2. 2. The − symbol is also commonly used to show a minus or negative number, such as −2.
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 used in spreadsheets and other computer applications to indicate a multiplication, although * does have other more complex meanings in mathematics. Less commonly, multiplication may also be symb...
These symbols are both used to mean division in mathematics. ÷ is used commonly in handwritten calculations and on calculators, for example, 2 ÷ 2. / is used in spreadsheets and other computer applications.
The = equals symbol is used to show that the values on either side of it are the same. 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. You may also come across other related symbols, although these are less common: 1. ≠ means not equal. For example, 2 + 2 ≠5 - 2. In compu...
This symbol means greater than, for example 4 > 2. ≤ ≥These symbols mean ‘less than or equal to’ and ‘greater than or equal to’ and are commonly used in algebra. In computer applications <= and >= are used. ≪ ≫These symbols are less common and mean much less than, or much...
This symbol ± means ‘plus or minus’. It is used to indicate, for example, confidence intervals around a number. The answer is said to be ‘plus or minus’ another number, or in other words, within a range around the given answer. For example, 5 ± 2 could in practice be any number from 3 to 7.
The ∑ symbol means sum. ∑ is the Greek capital sigma character. It is used commonly in algebraic functions, and you may also notice it in Excel - the AutoSum button has a sigma as its icon.
Degrees ° are used in several different ways. 1. As a measure of rotation - the angle between the sides of a shape or the rotation of a circle. A circle is 360° and a right angle is 90°. See our section on Geometryfor more. 2. A measure of temperature. Degrees Celsius or Centigrade are used in most of the world (with the exception of the USA). Wate...
The angle symbol ∠ is used as shorthand in geometry (the study of shapes) for describing an angle. The expression ∠ABC is used to describe the angle at point B (between points A and C). Similarly, ∠BAC would be used to describe the angle of point A (between points B and C). For more on angles and other geometric terms see our pages on Geometry.
