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.
Product[ <List of Numbers>, <List of Frequencies> ]
Calculates the product of all elements in the list raised to the value given in the list of frequencies for each one of them.
Examples:
Product[ {20, 40, 50, 60}, {4, 3, 2, 1} ] yields 1536000000000000
Product[ {sqrt(2), cbrt(3), sqrt(5), cbrt(-7)}, {4, 3, 2, 3} ] yields -420
Note: The two lists must have the same length.

CAS Specific Syntax

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.
