Subject: Calculating matrix permanent

I've read how to calculate the permanent of a matrix,
but I found the notation hard to understand so I'd
Like a practical demonstration. For 2 by 2 matrices
It's easy. For example, the permanent of


2 4
9 6

Is 2*6+4*9=36+12=48

But what about

5 3 1
8 2 4
7 9 6

What is48 the permanent of the above matrix
and how do you calculate it?
