Matrix Multiplication Step By Step

This animation breaks down matrix multiplication into its basic operation: each entry of the product matrix comes from multiplying a row of the first matrix by a column of the second and summing the results. Highlighted rows and columns move together to show which numbers combine, building the output matrix one cell at a time. Useful for students learning linear algebra fundamentals and for teachers introducing dot products and matrix dimensions before covering transformations.
