Sometimes the calculator on your computer can come in very handy, and Cortana in Windows 10 gives you access to a full featured calculator via the search box. Here’s how. With Cortana enabled:


  1. Tap the Windows key.
  2. Type your calculation into the search box.
  3. Cortana displays the result of your calculation at the top of the search results list.
  4. The calculator vanishes as soon as you click away.
