Matrices Addition and Subtraction:-
=============================
************************************************************************
Rule:
You can only Add or subtract two matrices only and only if they have the same number of rows and columns and the result will have the same number of rows and columns.
***************************************************************************
Addition or subtraction is performed between the two elements that have the same location.
Ex:
[ 5 4 [ 9 -3 [ (9+5) (4-3) [14 1
-1 6 + 8 2 = (-1+8) (6+2) = 7 8
0 7 ] -6 1 ] (0-6) (7+1) ] -6 8 ]
