The [[02 Areas/Digipen/Multiplicity.md|Multiplicity]] of an en element $x$ in a [[Multiset]] $X$ typically refers to the number of occurrences $x$ appears in $X$. The common usage is referring to to [[Roots|roots]] of a [[Polynomial]]. >[!example] >$ P(x)=(x-2)(x-2)(x-3) $ >The multiplicity of the root $2$ is $2$, while multiplicity of $3$ is $1$.
