Addition of matrices (sum of matrices) A + B is the operation of finding the matrix C, all of whose elements are equal to the sum of pairwise all relevant elements of the matrices A and B, that is, each element of the matrix C is

с_i,j = a_i,j + b_i,j

Subtraction of matrices (difference of matrices) A - B is the operation of finding the matrix C, all of whose elements are pairwise differences of all relevant elements of the matrices A and B, that is, each element of the matrix C is

с_i,j = a_i,j - b_i,j
