James listens to super-fast music.  It is 200 beats per minute.  He listens to 2 hours of music a day.  How many beats does he hear per week?
He listens to 2*60=<T>multiply(2, 60)=120 minutes of music a day
So he hears 200*120=<T>multiply(200, 120)=24000 beats per day
That means he hears 24,000*7=<T>multiply(24000, 7)=168000 beats per week
