The ≙ symbol, officially named "Estimates" in Unicode, is a mathematical operator featuring an equals sign topped with a small wedge or caret. It is primarily used in mathematics, physics, and engineering to indicate that one value estimates, corresponds to, or is defined as another. While rarely seen in casual texting or social media, it is essential in technical documentation where precise relationships between variables must be clearly expressed.
