Product[ <List of Numbers> ]: Calculates the product of all numbers in the list.
Product[ <List of Numbers>, <Number of Elements>]: Calculates the product of the first n list elements.

Example:

Product[{1, 2, 3, 4}, 3] yields 6.

In CAS View only the following syntax is allowed:

Product[ <List of expressions> ]: Calculates the product of all elements in the list.; Example:
Product[{1, 2, x}] yields 2x.

Product[ <Expression>, <Variable>, <Start>, <End> ]: Calculates the product of the expressions that are obtained by replacing the given variable with every integer from start to end.; Example:
Product[x + 1, x, 2, 3] yields 12.
