Calculator for calculating the sum and difference of two MxN matrices.

The addition of two matrices A and B is done by adding the elements of the matrices. C = A + B with c_{i, j} = a_{i, j} + b _{i, j}

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

Enter the matrix elements for matrix A: a_{1,1}, a_{1,2}, ...

Enter the matrix elements for matrix B: b_{1,1}, b_{1,2}, ...

The entered matrices are:
