The equals symbol or equal sign is used in mathematics to assert that two expressions have the same value. It is also used in boolean logic as an operator, evaluating true or false based on the two input expressions.
A well-known equality featuring the equal sign. The equals sign (British English) or equal sign (American English), also known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense.
The equal sign with two lines means something is equal to something. Example: a = 3, b = 9. The equal sign with three lines means that something is identical or similar to something but not necessarily equal. Thus, a triple equals sign means equivalent. The equivalent is not the same as ‘equals’.
Equals sign. The equal sign " = " is a symbol used to indicate equality. It looks like two parallel horizontal lines. Computers display the equals sign with the Unicode or ASCII character 003D (in hexadecimal ).
In 1557, Robert Recorde invented the equals sign, written with two parallel lines (=), because “noe 2 thynges, can be moare equalle”. “2 + 3 = 5” is much easier to read. Unfortuantely, the meaning of “equals” changes with the context — just ask programmers who have to distinguish =, == and ===.
As well as the familiar equals sign (=) it is also very useful to show if something is not equal to (≠) greater than (>) or less than (<)
The symbol “$=$” represents that the expression that is on the left side of the sign is exactly the same amount or value of the expression that is on the right side of the sign. We place an equal sign between two things that are the same or equal.
The = symbol is employed to indicate that two quantities or expressions are identical, meaning they represent the same value. Its use permeates almost every facet of mathematics, from basic arithmetic to advanced equations in higher mathematics.

The term equality, in mathematics, refers to the relationship between two quantities, or expressions, that says that they have the same value or represent the same object. The symbol used to denote this is the equals sign (=). For example: 2 + 2 = 4. (x - 2) 2 = x 2 - 4x + 4.
