Usage in mathematics and computer programming. In mathematics, the equal sign can be used as a simple statement of fact in a specific case (" x = 2 "), or to create definitions (" let x = 2 "), conditional statements (" if x = 2, then ... "), or to express a universal equivalence (" (x + 1)2 = x2 + 2x + 1 ").
Without proper rendering support, you may see question marks, boxes, or other symbols. The triple bar or tribar, ≡, is a symbol with multiple, context-dependent meanings indicating equivalence of two different things. Its main uses are in mathematics and logic. It has the appearance of an equals sign = with a third line.
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 types, many symbols are needed for ...
The symbol "=" is called an "equals sign". Two objects that are not equal are said to be distinct. For example: = means that x and y denote the same object. The identity (+) = + + means that if x is any number, then the two expressions have the same value.
The plus sign ( +) and the minus sign ( −) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition, which results in a sum, while − represents subtraction, resulting in a difference. [1] Their use has been extended to many other meanings, more or less analogous.
This article contains Unicode mathematical symbols. Without proper rendering support, you may see question marks, boxes, or other symbols instead of mathematical symbols. The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date.
In mathematics, an identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B (which might contain some variables) produce the same value for all values of the variables within a certain range of validity.
This attribute of a number, being exclusively either zero (0), positive (+), or negative (−), is called its sign, and is often encoded to the real numbers 0, 1, and −1, respectively (similar to the way the sign function is defined). [1] Since rational and real numbers are also ordered rings (in fact ordered fields ), the sign attribute also ...
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation. Notably absent are the plus sign (+), greater than sign (>) and less than sign (<), due to them already appearing in the Basic Latin Unicode block, and the plus-or-minus sign (±), multiplication sign (×) and obelus (÷), due to them ...
