I'm trying to write a contracted general equation for an expandable equation. Just like there's the summation symbol for sums, is there something for multiplying terms?

for example.. how do i contract the following?

$$C_{i}C_{ii}C_{iii}C_{iv}C_{v}...$$?

Similar to the symbol used for summations (upper-case sigma), there's another symbol that is used for products (upper-case pi).
$$\prod_{i = 1}^n C_i $$
This would be a product with a finite number (n) of factors.

If you meant this to be an infinite product, it would be
$$\prod_{i = 1}^{\infty} C_i $$

BTW, people generally don't use Roman numerals for indexes in mathematics expressions. What you wrote would usually be written as C1C2C3...
 
ah okay, thanks a lot mark44!
