Hi, Maybe someone can help me. When I define two matrices such as G={{1,2},{3,4}} and H={{5,6,},{7,8}} and then perform an operation such as multiplication, I get the correct result. But, if I add MatrixForm to each matrix first and then perform the operation, the operation is not evaluated. The output is simply two Standard Form expressions with no result. I appreciate any help.
