The Calculator app for Windows 10 is a touch-friendly version of the desktop calculator in previous versions of Windows.

You can open multiple calculators at the same time in resizable windows on the desktop and switch between Standard, Scientific, Programmer, Date calculation, and Converter modes.

To get started, select the Start  button, and then select Calculator in the list of apps.alternate text

Select the Open Navigation  button to switch modes. Use Standard mode for basic math, Scientific for advanced calculations, Programmer for binary code, Date calculation for working with dates, and options under Converter for converting units of measurement.alternate text

The calculator can help you calculate dates, convert currency, and if you're using the Standard mode, you can keep the calculator window on top of other windows.
