SUMMARY
Matrix multiplication is defined only when the number of columns in the first matrix equals the number of rows in the second matrix. For example, multiplying a 3x1 matrix (Matrix A) by a 1x3 matrix (Matrix B) results in a 3x3 matrix (AB). However, if these dimensions do not align, matrix multiplication is not possible. This fundamental rule is crucial for anyone working with matrices in mathematical computations.
