Question:
Max needs 65 paper plates for the barbecue party.  He already has 22 green paper plates and 24 blue paper plates. How many more paper plates does he need?
Answer:
He already has a total of 22 + 24 = <<22+24=46>>46 paper plates.
Therefore, Max needs 65 - 46 = <<65-46=19>>19 more paper plates.
