Any spreadsheet will do calculations by the use of formula. Create a new spreadsheet, put a number in cell A1, put a different number in cell A2, click in cell A3 and type in '=A2+A2', then press the Enter key. If you have done this properly then the spreadsheet will add any number entered into cell A1 to any number entered into cell A2. You can then save the spreadsheet for later
