Hey guys,

This is a question ithinkfits into L+AA subforum, if not, I do apologise!

I have two nbyn matrices, A and B. I need to specify the "number of operations" so I'm thinking (hoping) that will involve some sort of algebraic expression.

I've found so far:-

2x2 = 12 operations

3x3 = 45

4x4 = 112

5x5 = 225

Rubbish. All rubbish. Can anyone help me out?
