I really don't know what is your question pero sa Commutative Property po pagbabaliktarin lang ang dalawang factors. So: 7x3 = 21, 3x7 = 21.
Para saakin, the commutative property of multiplication to answer 7x3 is
7 x 3 and swap or baliktarin mo into 3 x 7. Now combine it 7x3=3x7
thanks po
7 x 3 now swap it = 3 x 7 .Now combined it 7 x 3 = 3 x 7
