its 91-19...so P is greater?

you know that:
so P is 8 greater than W.
P is larger.
by the way P=9, W=1
also you could have looked at it and noticed that if W were greater than P your answer would have to be negative. but your answer is positive, so it would be impossible for W to be greater than P leaving you with P is greater than W.

the answer is D. Since 72 is only 3 digits, that means that W+P can only equal 1 digit. There is no combination of Ws and Ps that can result in 72.

72 is 2 significant figures my friend, and the question isnt P*W-W*P, if it were it would always have to equal 0, the question is P as the tens digit W as the singles digit, minus, W as the tens digit P as the sigles digit. sorry neophyte youre taking one question turning it into another and then making it more confusing and incorrect than it was meant to be.
