Matrix addition is performed by adding corresponding entries. If two matrices have the same number of rows and columns, their sum is a new matrix where each element $(i,j)$ equals the sum of the elements at position $(i,j)$ in both original matrices.

Conditions: Both matrices must have identical dimensions (same $m \times n$).
