# Associative Property of Multiplication

(a + b) + c  =  a + (b + c)  (a × b) × c  =  a × (b × c)  ### Examples:

 This: (2 + 4) + 5  =  6 + 5  =  11 Has the same answer as this: 2 + (4 + 5)  =  2 + 9  =  11

### Examples:

 This: (3 × 4) × 5  =  12 × 5  =  60 Has the same answer as this: 3 × (4 × 5)  =  3 × 20  =  60
