If you calculate math formulas with a calculator you must remember them by heart. You have to key them in with all the operators and constants. In contrast, with CalcExpress, you enter the formula once and keep it for future use. Using a spreadsheet you have to write it all in one line… with CalcExpress, the expression is displayed in the usual mathematical form, and this way you can be sure you made no typing errors. In the CalcExpress Gold version, create your own a calculator out of math formulas. Display math formulas in the mathematical notation, and set up your own calculation environment! If you don’t like the standard background, you can specify the appearance of background and button in the dialogs. Select one out of five skins delivered with CalcExpress. You can also add your own skin! [Get more info | Download a trial ]
