product

    An expression in mathematics or
   computer programming consisting of two other expressions
   multiplied together.  In mathematics, multiplication is
   usually represented by juxtaposition, e.g. "x y", whereas in
   programming, "*" is used as an infix operator, e.g. "salary
   * tax_rate.

   In the most common type of product, each operand is a number
   (integer, real number, fraction or imaginary number)
   but the term extends naturally to cover more complex
   operations like multiplying a string by an integer (e.g., in
   Perl, "foo" x 2) or multiplying vectors and matrices or
   more than two operands.

   In type systems, a tuple is sometimes known as a "product
   type".
