Bryan bought three different bottles of milk. The bottles contain the following volumes of milk: 2 liters, 750 milliliters, 250 milliliters. How many liters of milk did Bryan buy in total?
Bryan bought a total of 750 + 250 = <T>add(750, 250)=1000 milliliters of milk from the two smaller bottles.
Since 1 liter is equal to 1000 milliliters, then 1000 milliliters is equal to 1000/1000 = <T>divide(1000, 1000)=1.0 liter.
Therefore, Bryan bought a total of 2 + 1 = <T>add(2, 1)=3 liters of milk.
