Use the Associative Property of Addition to find the total of 1, 10, and 18 in two different ways.

(1 + 10) + 18 = 11 + 18 = 29; (10 + 1) + 18 = 11 + 18 = 29
1 + 10 + 18 = 11 + 18 = 29; 18 + 10 + 1 = 28 + 1 = 29

1 + 10 + 18 = 11 + 18 = 29; 10 + 18 + 1 = 28 + 1 = 29

(1 + 10) + 18 = 11 + 18 = 29; 1 + (10 + 18) = 1 + 28 = 29

Question

Use the Associative Property of Addition to find the total of 1, 10, and 18 in two different ways.
 	
(1 + 10) + 18 = 11 + 18 = 29; (10 + 1) + 18 = 11 + 18 = 29
1 + 10 + 18 = 11 + 18 = 29; 18 + 10 + 1 = 28 + 1 = 29

1 + 10 + 18 = 11 + 18 = 29; 10 + 18 + 1 = 28 + 1 = 29

(1 + 10) + 18 = 11 + 18 = 29; 1 + (10 + 18) = 1 + 28 = 29

Two of the answers move order of the numbers, that is "commutes" them. Think about "commuting to work"; you go from place to place.

Two of the answers group the numbers, that is, they cause certain numbers to "associate" with each other in pairs.


Find one of the answers that causes the numbers to associate in DIFFERENT ways.
