Matrix Associativity Testing
In algebra classes we a taught that matrix multiplication is associative: A(BC) = (AB)C. In actual computer computations with large matrices this associative property often fails. In some situations with disasterous effects. This spreadsheet tests 1x1 through 5x5 matrix multiplication on randomly generated matricies to demonstrate the failure rate for associativity of matrix multiplication.
