The equal sign or equal sign, formerly known as the equality sign, is the mathematical symbol =, indicating equality in some well-defined function. For example, in an equation, it is located between two expressions with the same value, or for which one analyses the conditions under which they have the same value.
- In mathematics, the equal sign (=) describes equality between the values, equations, or expressions written on both sides. For example: 17 – 11 = 6
