After installing many calculators, this one is the only one that I kept. It is simple to use, keeps a running history, and has all the functions I need. A professional engineer, now retired with modest computing needs, when I do need something more capable, I write a program on the Mac. Especially on the iPod, to begin something more complicated with a calculator is a little foolish. Good Grapher is well worth the money. It is also the one I use for simple daily, household needs.
