State the necessary condition for two matrices to be added.Intuitive explanation
Matrix addition is about combining entries that are in the same position. For this to work, both matrices must have identical dimensions—the same number of rows and the same number of columns. Without this match, there's no way to pair up corresponding elements, so the operation is undefined. Think of it like aligning two grids: they have to be the same shape for element-by-element addition to make sense.
