product
<mathematics, programming> 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".
