Comments:
I use a ton of it as a nurse. In nursing school everyone complained about how the pharmacy and pumps do most of the math work for you. Which is true for a lot. But when I'm calling the physician and can safely give up to 20 mEq of postassium per hour IV, and we've got fluids with potassium and we want to figure out how much we can add on top of that, well, a little math comes in handy figuring all that out. I've taken higher levels of math than I really use on a daily basis, but the problem solving you learn sticks with you after the calculus equations are gone. As for calculators, I'm a total math in my head and on paper nerd. I'll work it out on paper if it's handy before I'll go searching for a calculator. Even long division. I'm too lazy to look for calculator unless it's got lots of decimals, or it involves my bank balance.
