The "Not Equivalent To" symbol (≭) is a mathematical operator featuring an "equivalent to" sign (≍) struck through with a forward slash. Mathematicians and logicians use it to state that two expressions, sets, or geometric figures do not share a specific equivalence relation. While casual internet users generally rely on the standard "not equal to" (≠) sign, this particular character is essential in technical fields where equality and equivalence represent entirely distinct concepts.

In Programming

While rarely used directly in source code—where developers prefer standard inequality operators like `!=` or `!==`—this symbol is frequently generated in mathematical markup systems like LaTeX to denote a lack of equivalence.
