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