RUCalc is a great little calculator for the home or office. All the basic mathematical functions are there, along with +Tax and -Tax for adding and subtracting tax from your figures at the click of a button or the press of a key. (The actual tax amount is also displayed in the status bar at the bottom.)

Three memory banks are included, which can retain their values between sessions if you like.

Some simple-to-use programmable functionality is also available, allowing you to perform long repetative calculations with ease. A few handy functions are already included to start you off.
