Simple calculator launch 1 button NumLock - Windows Shareware $5. The main idea of our project is "Comfort is the first". This calculator is not a scientific or an engineering one. It is a basic calculator for everyday usage. But as it often happens, merits and demerits change their places. When did you use all that scientific or engineering functions? They are just useless in everyday counts. But you do remember, how long it takes to launch any installed calculator.

What we really offer you is: "With one press you can count, with another it gets out". We are sure, this feature will be useful indeed. Another thing that seemed inconvenient is the size of the figures in the display area. With this calculator: "You even dont have to look, in order to see". We tried to take care of your sight. And the third feature that seemed rather actual for us is the hide/restore function for keyboard panel. Somebody uses a mouse to click the keys on the virtual keyboard, but it is much more comfortable to use NumLock keys. In that case you can just hide the virtual keyboard panel to minimize a size of the calculator. "Large figures for lesser size". It leaves more space for your other documents, working simultaneously.
