Windows Calculator Tips

Tip: By default, the Windows Calculator is set to Standard mode. The mode can be changed by clicking View in the top menu, then choosing Scientific. Scientific mode gives the user more options and abilities.

Note: In Windows 10, Calculator does not have a top menu. Instead, click on the button with three horizontal lines stacked vertically, near the top left of the window, and select Scientific.

Tip: By default, digit grouping in the Windows Calculator is disabled. Enabling this feature causes your long numbers to have commas. For example, instead of 10000000, it would display as 10,000,000. To enable this feature, click View in the top menu and select the Digit grouping option.

Note: In Windows 10, the Calculator uses digit grouping by default.

As can be seen in the picture, there are several new features that have been highlighted and are not available in previous versions of Windows.
