The Not Equal To (≠) symbol is a mathematical operator used to indicate that two values or expressions are not equivalent. Originating from traditional mathematical notation, this character simply adds a forward slash through a standard equal sign. Beyond algebra and formal logic, it frequently appears in digital communication and social media to contrast two ideas or emphasize a strict difference.
