Associative Property of Addition

This property says that when adding 3 terms, changing the order of operations does not change the outcome. More precisely:

(a + b) + c = a + (b + c)

Here are some examples:

(5 + 7) + 9 = 5 + (7 + 9)

(x + 1) + z = x + (1 + z)

((mn) + 2) + (jk) = (mn) + (2 + (jk))
