The ≂ symbol, officially known as the Minus Tilde, features a standard minus sign positioned directly above a tilde. In mathematics and formal logic, it is primarily used to indicate equivalence, approximation, or a specific binary relation between two elements. While rarely used in casual everyday writing, it remains a vital notation in advanced algebra and scientific documentation to express that values are roughly equal or share a defined relationship.
