Adding or subtracting matrices is simple and can be accomplished by adding/subtracting the corresponding matrix elements:
c_{rs }:= a_{rs }+ b_{rs},
with C, A, and B being the respective matrices. The order of the matrices A and B must be the same. Matrices of unequal order cannot be added or subtracted.
The zero matrix 0 naturally arises from subtracting two indentical matrices and contains only zero elements.
A - A = 0
Let's take a look at an example:
