Randy had some money. Smith gave him another $200. Randy then gave Sally $1,200 and kept the rest. If Randy has $2000 left, how much money, in dollars, did Randy have at first?
After Smith gave him $200, Randy had 2000+1200=<T>add(2000, 1200)=3200 dollars.
Randy had 3200-200=<T>subtract(3200, 200)=3000 dollars at first.
