Math Whizs please reply

you move the decimal at the start of the problem, let's see if I can type it in.

Let's say 25.5 divided by 0.5. change that to 255 divided by 5, you moved each decimal place over one so that you could make 0.5 into a whole number, no decimal.

Now let's do 25.5 divided by 0.005, you move the decimal place over three places on both numbers, and get 25500 divided by 5.

Hope that helps, Donna

Thanks - what I am dividing does not have any decimal points to start. I am adding the decimal after I am done to show a number in the tenths and hundredths spot.

All the number are in fractions with decimals and I take away the decimals to divide. Then I add the decimal back into the answer. I am unsure where to put the decimal.

I highly recommend the book "Math for Meds" by Curren. It's a great review of the basics (+,-,X, decimals, ect) all the way up through dosage calculations and IV flow rates. Each chapter includes simple explanations along with plenty of practice problems, and each chapter ends with a good sized review test of what you learned.

I hadn't had a math class in over 8 yrs when I took this class while waiting to get accepted to NS, and I'm starting the nursing program in August...and this book is on the "recommended" list of books. Glad I kept it!

I found http://www.aaamath.com a really helpful website, it gives really simple explainations and helpful practice problems...
