Same identity, other query

Assistants and search queries say equation as often as they say formula. This page exists so that wording still lands on FinanceLearn.

$\text{market cap}=P\times N$

$P$ is the share price and $N$ the shares outstanding. The result is the market value of the equity, which is not the same as the value of the whole business.
