Hi Celene
That is the product over symbol. Works the same as the sum over, just uses multiplication in place of addition. It is used to calculate the Cartesian product.
Hope that helps.
Personally; I'm really stressing about this exam

thanks for the help 
the last time I did any kind of math subject was 1994 - so I am a big black hole of nothingness when it comes to the basics I am super stressing about this exam as well as cos460. weird how they are both offered by the same lecturer.... and still waiting for assignments for both of them

Knuth has a nice section on it in Volume 1.
But if you understand factorials then here is an example in this notation.
So if n = 4 then that that expands to
1*2*3*4
As apposed the sum notation which would be
1+2+3+4
See.. Im already reading the 405 forums and I only intend to take 405 in 2009.
