Longhand is a calculator built from the ground up to facilitate calculation. Most other computer calculators try blindly to emulate the physical format of their predecessors.

Longhand is exceptionally easy to use, but is also surprisingly powerful.

What works well in the real world, however, functions worst, and is often not desired, in its virtual sibling. By leveraging the capabilities provided by modern technology, Longhand allows you to perform everything from the most basic to the most complex of calculations with great ease.

Longhand uses the same paradigm as a word processor. You simply type in equations instead of hunting and pecking virtual calculator buttons. As your equation is entered, Longhand dynamically calculates the answer. Made a mistake with your math?

No problem. With a usual calculator you would have to retype your equation, but with Longhand you can simply correct it! The calculator for calculators...

It supports all the standard arithmetic functions, but in addition to that Longhand has superb handling of trigonometry, multiple bases (binary, hexadecimal, etc.), matrices, complex numbers, and much more. Longhand is also highly accurate with support for arbitrarily long numbers instead of limiting you to the built-in number size of your OS.
