Mental Math Situation: You exercised 24 hours each month for a year. How many hours did you exercise by the end of the year? You may be able to do the math mentally thanks to expanded notation and the Distributive Property.

So 24 hours each month times 12 would be 288 hours of working out of one year.

Hope this helps!
