Chalkboard Calc 3

Chalkboard Calc 3 is such an easy to use and effective "calculator" which enables you to describe equations the way you would with traditional paper and pencil. Only now, the number crunching is done for you, right as you type.

Chalkboard has many features that are both highly convenient and functional. Instead of having to memorize numbers, all you have to do is assign them to a Variable for later use. Or perhaps you have a complex equation that's always hard to remember? Now, just create a function for it and you'll never have to worry about it again.
