 Jun 18, 2010 Math Moves by: Keith In Pharmacy Tech math, I recommend that you first write down your factors in a very organized way before you even determine which method you will use to solve the problem. I say this because most of them are situational word type problems and there are usually 2-3 ways to solve them.After that, you really just have to pick which way you will need to go. The best way to do this is by practicing alot of Math problems. Repetition will train you to remember "Math Moves" I know that sounds terribly trite, but it's really the only way.Additionally, you'll find that basic Math (addition, sub., Mult. Div) and proportions math covers the majority of the problems you encounter.I believe that the only real secret to doing the math better is to 1)not ever rush a math problem and 2)stay very organized.If anyone else has ideas to remember the best methods to tackle Math Problems please add a comment using the link below

 Nov 14, 2010 Make sure the units are right by: Anonymous Organization is key to this, and neatness helps. Check what units they are giving you and what units they are asking you for. Do any necessary conversions to get to the proper units asked for and make sure everything else cancels out. Always write down your units. Another thing is to make sure that the information given in the problem is necessary to solve it. Many times they give superfluous information in an attempt to confuse you. Don't get confused; eliminate extra info and use only what you need to solve the problem.

 Nov 20, 2010 Dimensional Analysis Method for math formula by: Darcetha I am also studying for the PTCB exam and math has always been my weakness. After doing some internet research, I found this article that explains math formulas, it is called Medication Math A self-Learning Module for 1st Semester Associate Degree Nursing Students. It is very informative and easy to understand.The formula that works for me is the Dimensional Analysis Method. This method is actually the preferred way to solve medication math problems. It is a method of factor analysis or units conversion that is widely used in physics and chemistry. Hope this helps.
