Which of the following is not a correct statement or outcome for multiplying matrices?
a. In order to multiply matrices, number of columns in first matrix = number of rows in second matrix.
b. The matrix outcome is number of rows in first matrix by number of columns in second matrix.
If matrix 1 has dimensions (r1, c1) and matrix 2 has dimensions (r2, c2), their product can be formed if c1 = r2. The resulting product matrix will have dimensions (r1, c2).
