The multiplication of ]https://en.wikipedia.org/wiki/Integer integers] (including negative numbers), [https://en.wikipedia.org/wiki/Rational_number rational numbers] (fractions) and [https://en.wikipedia.org/wiki/Real_number real numbers] is defined by a systematic generalization of this basic [[definition]].

''Multiplication'' can also be [[visualized]] as counting objects arranged in a [https://en.wikipedia.org/wiki/Rectangle rectangle] (for whole numbers) or as finding the area of a rectangle whose sides have given lengths. The area of a rectangle does not depend on which side is measured first, which illustrates the commutative property.
