## Summary

In mathematics, **equality** is a relationship between two quantities or expressions, stating that they have the same value, or represent the same mathematical object. Equality between $A$ and $B$ is denoted with an equals sign as $A = B$, and read "$A$ equals $B$". A written expression of equality is called an equation or identity depending on the context. Two objects that are not equal are said to be **distinct**.
