How To What is this math symbol: 9 Strategies That Work

$$:=$$ is the commonest symbol to denote "is equal by definition." Note that $$\equiv$$ is used to denote an algebraic identity: this means that the equation is true for all permitted values of its variables. Rarely, however, it may denote a definition, so it's best to use this symbol only for congruences or identities.A multiplication symbol inside a circle.
