ATCalc is a complete graphic calculator that works to view, and optionally to copy to the Windows clipboard, all calculations, variables and results used in any operation. It also includes a programming setting to tackle the more difficult calculations.
ATCalc lets you write all the calculations you want in only one line. Thus you can see and write, for example, (12*3)/(4+2+8) and later revise it if it isn“t correct before processing it. This is the most important difference between ATCalc and other similar programs you could use.
