## Matrix multiplication

### Multiplication of two matrices MxN and NxJ

$A\cdot B=\left(\begin{array}{cccc}{a}_{11}& {a}_{12}& \dots & {a}_{1n}\\ {a}_{21}& {a}_{22}& \dots & {a}_{2n}\\ & ⋮\\ {a}_{m1}& {a}_{m2}& \dots & {a}_{mn}\end{array}\right)\cdot$

$\left(\begin{array}{cccc}{b}_{11}& {b}_{12}& \dots & {b}_{1n}\\ {b}_{21}& {b}_{22}& \dots & {b}_{2n}\\ & ⋮\\ {b}_{m1}& {b}_{m2}& \dots & {b}_{mn}\end{array}\right)$

Number of rows M from A =

Number of columns N from A =

Number of columns J from B =

Number of digits =

### Product of the matrices:

$A\cdot B=C=\left(\begin{array}{cccc}{c}_{11}& {c}_{12}& \dots & {c}_{1j}\\ {c}_{21}& {c}_{22}& \dots & {c}_{2j}\\ & ⋮\\ {c}_{m1}& {c}_{m2}& \dots & {c}_{mj}\end{array}\right)$
