Calc Pro

Calc Pro is a calculator that can help us make mathematical operations. At first sight, this application displays an elementary user interface that resembles that of a typical calculator.

But, after reading the help file, we get to know that this program can offer us more than just an easy way of solving simple mathematical problems. Actually, if we press the space bar, a new window will pop up that will display all the operations we are doing, exactly as if we were typing them on a piece of paper. In addition to this nice feature, it is possible to save the content of that new window as a text file, and edit/print/send it with the help of external applications. In other words, we may perform basic math operations and have them nicely presented.

Although the fully-featured evaluation version is valid for a long time (thirty days in total), we are only let to open/close the calculator three times. The only disadvantage that I found is that every time we set to open the trial version, we must wait for 10 seconds to be able to close the initial window. This program runs under Windows Vista, XP, 2000, ME, NT, and 98 operating systems.
