Real-valued matrices up to 6 × 6. Matrix multiplication is ordered: A × B generally differs from B × A.
Each result entry is the dot product of a row of A and a column of B.
For A × B, each output entry is a row-column dot product. A’s column count must match B’s row count; addition requires identical dimensions.
Multiplying [[1, 2], [3, 4]] by [[5, 6], [7, 8]] gives [[19, 22], [43, 50]].
Yes. A × B generally differs from B × A, and one order may be undefined even if the other is valid.
