The <rank-nullity theorem> for a <linear map> $T:V\to W$, with $V$ a <finite-dimensional vector space> over a <field> $F$, is
$$
\boxed{\dim_F V=\dim_F\ker T+\dim_F\operatorname{im}T.}
$$
Here the <nullity> is the <dimension> of the <kernel of a linear map>, and the <rank of a linear map> is the <dimension> of its <image of a linear map>.
