Joey studies for his SAT exams 2 hours per night 5 nights a week.  On the weekends, he studies 3 hours a day.  If his SAT exam is 6 weeks away, how much time will Joey spend studying?
Joey studies 2 hours a night 5 nights a week so that's 2*5 = <T>multiply(2, 5)=10 hours
He studies 3 hours a day on the weekends so that's 3*2 = <T>multiply(3, 2)=6 hours
In one week, Joey studies 10+6 = <T>add(10, 6)=16 hours
He has 6 weeks till his exams and he studies for 16 hours a week so that's 6*16 = <T>multiply(6, 16)=96 hours of studying
