John joins a country club with 3 other members of his family.  The fee to join is $4000 per person.  There is also a monthly cost of $1000 per person.  John pays half the cost.  How much does John pay for the first year?
There are 3+1=<T>add(3, 1)=4 members joining
So the cost is 4*4000=$<T>multiply(4, 4000)=16000 to join
The monthly fee comes out to 1000*12=$<T>multiply(1000, 12)=12000 per person per year
So that is 12000*4=$<T>multiply(12000, 4)=48000
So the total cost is 16,000+48,000=$<T>add(16000, 48000)=64000
So John pays 64000/2=$<T>divide(64000, 2)=32000.0
