What does symbol mean

Hi,

Often in my notes there is what look likes a large pi sign. I found matching notation on this site in the section "The likelihood function - Proof"

Normal distribution - Maximum likelihood estimation

Please can someone explain what it means or point me to some wiki page.

Thanks

It's like summation, except you find the product instead of the sum of all the elements.
Thanks from calypso
