Calculator

Calculator is an application that solves mathematical equations and is suitable as a default application in a Desktop environment.

What Calculator is:

A tool for calculating mathematical equations
Uses standard mathematical notation where possible (so users do not have to learn the application when they already know maths)
Easy enough to use for simple maths (add, subtract, multiply, divide)
Powerful enough for mid-level mathematics (though not at the expense of being easy for simple mathematics)
Fast to load and responsive to input
Appropriately sized to fit into standard screen resolutions (e.g. netbooks)
Fully accessible
Well documented
Integrated into the GNOME Desktop

What Calculator is not:

It does not emulate any existing calculator interfaces, hardware or software (use those calculators if you want this behaviour)
It is not a power-tool for professional mathematicians (professionals should use a specialist application)
It is not a programming language (programmers should use a programming language)
