Definition

The "Not Equal To" symbol (≠) is used to indicate that two values are not equal.

Description

The "Not Equal To" symbol is crucial in mathematics as it denotes inequality between two expressions. This symbol is used in various mathematical contexts, such as solving inequalities, comparing numbers, and expressing conditions in algebraic equations. For example, in the inequality 𝑥 ≠ 5, it means that x can be any number except 5.

In real-world applications, the "Not Equal To" symbol is used in programming, data analysis, and logic to set conditions and filters. For instance, in a database query, one might use ≠ to exclude certain values from a dataset. Understanding this symbol is fundamental for students as it lays the groundwork for more complex mathematical concepts and logical reasoning.
