Those of us who feel more attracted by books may have enough with the Windows Calculator, but mathematics people definitely need something more. Here's where Derive 6 comes in handy by presenting you with a wide variety of mathematical tools ready to perform almost any kind of maths operation.

The program displays a blank interface where you insert numbers, expressions, symbols and everything you need to create your calculations. The data is entered through a command line and added in consecutive lines on the program's interface. Besides using your keyboard, you can also use the program's buttons to enter certain symbols which may be harder to find on your keyboard configuration. You can then let Derive solve the problem and also get it printed on paper for further study.

All the operators and commands are conveniently categorized into a menu which, together with a comprehensive help system, make the program very complete and easy to use – that is, if you have some basic maths knowledge. Otherwise, you may as well stick to the Windows Calculator!
