Question 135211: Is this right?
Use the commutative law to find an equivalent expression zy.
Is it z.x?
Thank you for your time. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Commute means to change places.
zy commutes to yz
Similarly z+y commutes to y + z
But z-y does not commute to y-z because 5-2 is not the same as 2-5
