Associative Property of Addition

 

 

 

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
