May 2, 2024 · Algebra: The branch of mathematics that substitutes letters for numbers to solve for unknown values. Algorithm: A procedure or set of steps used to solve a mathematical computation. Angle: Two rays sharing the same endpoint (called the angle vertex). Angle Bisector: The line dividing an angle into two equal angles.

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.
Jargon often appears in lectures, and sometimes in print, as informal shorthand for rigorous arguments or precise ideas. Much of this uses common English words, but with a specific non-obvious meaning when used in a mathematical sense. Some phrases, like "in general", appear below in more than one section.
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y.

Solved Examples on Math Symbols. 1. Express using different math symbols: i) the sum of a and b. ii) eight times y. iii) x to the power of 5. Solution: i) The expression “sum of a and b” refers to the addition of the terms “a” and “b.” Sum of a and b $= a + b$ ii) eight times y. Eight $= 8$ Here, y is a variable.
