Ten boys brought 15 popsicle sticks each. Twelve girls brought 12 popsicle sticks each. How many fewer popsicle sticks did the girls bring than the boys?
The boys brought a total of 10 x 15 = <T>multiply(10, 15)=150 popsicle sticks.
The girls brought a total of 12 x 12 = <T>multiply(12, 12)=144 popsicle sticks.
Therefore, the girls brought 150 - 144 = <T>subtract(150, 144)=6 fewer popsicle sticks than the boys.
