Calculator is a program that comes with every Windows computer. It’s ok for the simplest of calculations, but it has a lot of limitations. For example, it doesn’t keep a history of your calculations and there is no way to keep it floating on top of the screen. SpeedCrunch is a good alternative to Calculator. SpeedCrunch keeps a running history of your calculations, has syntax highlighting, let’s you create variables, and has many other features. You can download SpeedCrunch here. It’s free, and I recommend you get the portable version.
