The second equation is simplified though the communitive property of addition (where the order in addition problems don't matter) and the third equation is the associative property of addition (where you can group any values in addition problems together).

(9 + 23) + 11 = 9 + 11 + 23 = (9 + 11) + 23 = 43 Identify what properties were used to simplify.
