Formulas

Function over fashion explains a lot about the world of science (especially pocket protectors.) This little program isn't very pretty to look at, but it comes with a powerful brain behind it. The main drawback of Formulas is its DOS interface (almost as rare as an 8-track, these days.) While this interface may deter many users from diving in, we found that once you get the hang of the program, its looks are secondary. Formulas does take a few liberties; it automatically installs on your C: drive, but doesn't inform you of this. To perform a calculation, follow the onscreen directions that outline when to input values and choose parameters. Results are displayed very quickly, and accurately. Once you've got your answer, you can cut and paste the details into another program window. If basic formulas tie you up in mental knots, this basic yet powerful program might be the detangler you need.
