This can be represented as: If we think of \(P= [p_{ij}]\) as a matrix of order m n, then the additive identity of P is the zero[O] matrix of order m n in such a way that P + O = O + P = P. Hence we can say that the zero matrices are the additive identity for the given matrix. In the same way, the addition of two matrices can be done by the addition of related terms in the matrix. \end{matrix} {x y}&{2x + z}\\ Matrixes can be added, subtracted, and multiplied, but they cannot be divided.

As discussed before, for the matrix addition, the order of the matrices should be the same so that all corresponding elements can be added. However, unlike the arithmetic addition of numbers, matrix addition follows distinct rules as discussed below: Consider some examples to understand the same. \begin{matrix} x23 + y23 = -19 + 30 = 11. Example 3. No, it is not possible to add matrices of Different Dimensions. \end{array}} \right]\), The elements of any row can be added with the corresponding elements of another row which is multiplied by a non-zero number. \right] The addition of matrices can be done in ways like the element-wise addition of matrices and the direct sum of matrices. Matrices to be added should have the same dimension. Matrices are available in all varieties of sizes and the size of a matrix is termed its dimension which is the total number of rows and columns in an assigned matrix. \end{array}&\begin{array}{l} {\frac{2}{5}}&{\frac{{ 12}}{5}}\\ 7&{24}\\ /MediaBox [0 0 792 612] To add two or more matrices, those matrices must have the same order. /XIPLAYER_CM3 11 0 R 2&{ 2}\\ In simpler words, to add two matrices, they must have the same number of rows and columns.
