# Associative Property of Multiplication

Pronunciation: /əˈsoʊ.siˌeɪ.tɪv ˈprɒp.ər.ti ʌv ˌmʌl.tə.plɪˈkeɪ.ʃən/ Explain

The associative property of multiplication states that, when multiplying three numbers, it does not matter in which order they are multiplied.[2] This is expressed by the equation: a·(b·c) = (a·bc.

One way to remember the associative property of multiplication is to use the root word, 'associate'. So in the associative property of multiplication, the variables b and c associate closely on one side of the equals, while a and b associate closely on the other side.

A representation of the associative property of multiplication using dots is:

 Figure 1: 3·(2·4) = (3·2)·4 = 24.
