    This is annoying because I know I used to know this but for the life on me I can't remember.

    And I'm not sure what to google for.

    What is the meaning of a Capital "PI" greek letter in an expression. The type of expression I'm refering to look a lot like the sumation expressions that use a greek capital "sigma".

    Thanks.

    It means product. In the same way as \(\Sigma\) means sum, \(\Pi\) means product.
