matrix_sum(`[[3;1;-5];[3;2;1];[4;0;1]];[[3;1;2];[3;4;1];[4;0;1]]`) returns `[[6;2;-3];[6;6;2];[8;0;2]]`

This matrix calculator allows to calculate online the sum of two matrix with calculation step.

The calculator can calculate online the **sum of two matrices**.
The **matrix calculator** may calculate the **sum of matrices** whose coefficients have letters or numbers,
it is a formal matrix calculation calculator.

The calculator can **calculate the sum of two matrices** with the results in exact form:
to calculate the sum of matrices `((3,3,4),(1,2,0),(-5,1,1))+((3,3,4),(1,4,0),(2,1,1))`, enter
matrix_sum(`[[3;1;-5];[3;2;1];[4;0;1]];[[3;1;2];[3;4;1];[4;0;1]]`),
after calculation, the result is returned.

The calculator allows symbolic calculations, it is possible to use letters as well to **calculate the sum of two matrices** like this:
`((a,3),(a/2,4))+((a,1),(a/2,2))`, enter
matrix_sum(`[[a;a/2];[3;4]];[[a;a/2];[1;2]]`),
after calculation, the result is returned.

matrix_sum(matrix;matrix)

matrix_sum(`[[3;1;-5];[3;2;1];[4;0;1]];[[3;1;2];[3;4;1];[4;0;1]]`) returns `[[6;2;-3];[6;6;2];[8;0;2]]`
