So what's the plan? you ask. The plan is to carefully go through the unit cancellation tutorial. Work out the problems on paper as they are presented to you. Use a calculator so you aren't distracted by long hand arithmetic. Remember, you are not learning arithmetic; you are learning how to make medical conversions. Learn how to use your calculator. Become comfortable with it so when you begin your work as a medical caretaker or technician you will have command of your tools.
