Use the Associative Property of Addition to find the total of 4, 12, and 18 in two different ways.
4 + 12 + 18 = 16 + 18 = 34; 18 + 12 + 4 = 30 + 4 = 34

(4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34

(4 + 12) + 18 = 16 + 18 = 34; (12 + 4) + 18 = 16 + 18 = 34

4 + 12 + 18 = 16 + 18 = 34; 12 + 18 + 4 = 30 + 4 = 34

4, 12, and 18 in two different ways

(4 + 12) + 18 = 16 + 18 = 34
 
4 + (12 + 18) = 4 + 30 = 34

answer is B) (4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34 (second choice)
