The commutative property of addition is the idea of adding any two (or more) numbers in any order we want. In the example above, the 3 and 5 swap places. You can think of them commuting back and forth as if they are going from work to home (or vice versa).
A similar property is the commutative property of multiplication. An example would be 2*3 = 3*2 (shown in choice B).
