A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. The numbers in a matrix are called its elements or entries. A matrix with mmm rows and nnn columns is called an m×nm \times nm×n matrix, read as “m by n matrix”.
Addition of Matrices : Matrix addition is a binary operation that takes two matrices of the same dimensions and produces another matrix of the same dimensions, where each element of the resulting matrix is the sum of the corresponding elements of the input matrices.
Subtraction of Matrices : Matrix subtraction is a binary operation that takes two matrices of the same dimensions and produces another matrix of the same dimensions, where each element of the resulting matrix is the difference of the corresponding elements of the input matrices.
