Diane bakes four trays with 25 gingerbreads in each tray and three trays with 20 gingerbreads in each tray. How many gingerbreads does Diane bake?
Four trays have 4 x 25 = <T>multiply(4, 25)=100 gingerbreads.
And three trays have 3 x 20 = <T>multiply(3, 20)=60 gingerbreads.
Therefore, Diane bakes 100 + 60 = <T>add(100, 60)=160 gingerbreads.
