Out of the 120 people who attended the party, 1/3 are men while half are women. The rest are children. How many children attended the party?
There were 120/3 = <T>divide(120, 3)=40.0 men at the party.
There were 120/2 = <T>divide(120, 2)=60.0 women at the party.
So, there were 40 + 60 = <T>add(40, 60)=100 men and women at the party.
Thus, 120 - 100 = <T>subtract(120, 100)=20 were children.
