Tim takes his 3 children trick or treating.  They are out for 4 hours.  Each hour they visited 5 houses.  Each house gives 3 treats per kid.  How many treats do his children get in total?
They visit 4*5=<T>multiply(4, 5)=20 houses
That means each child get 20*3=<T>multiply(20, 3)=60 treats
So in total they get 60*3=<T>multiply(60, 3)=180 treats
