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".

It has been shown that SFC in plasma from patients with DIC exists as complexes with a variety of fibrinogen derivatives, including intact fibrinogen as well as early and late fibrin degradation products.
Because tissue factor-induced thrombin formation is a cardinal feature of ACS (7, 8), a promising approach to find early markers for ACS involves the measurement of fibrin formation and fibrin degradation products.
Fibrinogen equivalent units express the concentration of fibrin degradation products in terms of the gravimetrically determined mass of fibrinogen from which they were derived.
