Mike watches TV for 4 hours every day.  On the days he plays video games he plays for half as long as he watches TV.  If he plays video games 3 days a week how long does he spend watching TV and playing video games?
He plays video games for 4/2=<T>divide(4, 2)=2.0 hours a day
He watches TV for 4*7=<T>multiply(4, 7)=28 hours a week
He plays video games for 3*2=<T>multiply(3, 2)=6 hours
So in total he spends 6+28=<T>add(6, 28)=34 hours on those activities
