The Windows Calculator is one of those features that has been around for a long, long time. For the most part it gets unnoticed until you need to do some basic calculations.
To quickly bring up the calculator, from the Start screen type CALC and select the calculator icon, or from the Run... command (WinKey + R) type: CALC.EXE.
When you first start-up calculator it will look like it always does, with just the basic features. To access the more advanced modes (such as the unit or date conversion, and worksheets), open up the File menu or use the keyboard shortcuts below:
Available calculator modes:
- ALT+1: Standard
- ALT+2: Scientific
- ALT+3: Programmer
- ALT+4: Statistics
- CTRL+H: Enable the history feature
- CTRL+U: Unit Conversion
- CTRL+E: Date Conversion
Note: To access the mortgage, vehicle lease and fuel economy worksheets, from the File menu, select Worksheets then select the one you want to use. To revert the calculator back to its default functionality, press CTRL+F4.
Bonus Tip: It is pretty easy to assign a special key combination to the calculator's shortcut (just right-click the program's icon (in the File Explore, go to "%ProgramData%\Microsoft\Windows\Start Menu\Programs\Accessories\" and select Calculator.lnk) select Properties, and click in the Shortcut Key field, then assign a keyboard combination such as Ctrl + Alt + C, and then press the OK button)
