John works at 2 different hospitals.  At the first hospital, he sees 20 different patients each day.  At the second hospital, he sees 20% more individual patients a day.  He works 5 days a week.  How many patients does he treat a year if he works 50 weeks a year?
He treats 20*.2=<T>multiply(20, 0.2)=4.0 extra patients
So he treats 20+4=<T>add(20, 4)=24 patients at the second hospital
So he treats 20+24=<T>add(20, 24)=44 patients a day
That means he treats 44*5=<T>multiply(44, 5)=220 patients a week
So he treats 220*50=<T>multiply(220, 50)=11000 patients a year
