Product (mathematics)


Product (mathematics)

In mathematics, a product is the result of multiplying, or an expression that identifies factors to be multiplied. The order in which real or complex numbers are multiplied has no bearing on the product; this is known as the commutative law of multiplication. When matrices or members of various other associative algebras are multiplied, the product usually depends on the r of the factors. Matrix multiplication, and the multiplications in the other algebras, are non-commutative.

The product operator for the product of a sequence is denoted by the capital Greek letter Pi (in analogy to the use of the capital Sigma as summation symbol).

Several products are considered in mathematics:
