TheCalcMan

99% of the users use calculators for doing simple calculations. And most use the Windows Calculator. How do you use it:

You first type the first number from the keyboard. Then you choose the operator using the mouse. Then again you use the keyboard to enter the second number.

It causes annoyance to move your hand from keyboard to mouse and to keyboard again, doesn't it?

This is why TheCalcMan was created. It has a text box to enter the WHOLE expression(eg 2+3) and then you press enter. And you get your answer. Yes it's that simple.

It is a small app. It has got visual effects too. Apart from the four operators it supports Exponentiation and Factorial. It combines the power of command line apps with the usability of GUI apps.

It supports constant operator (for doing 2+3+4+5+6+7 or 2*3*4*5*6 and like that).
