Calculator App in Windows 10 is a touch-friendly version of the desktop calculator in previous versions of Windows, and works on both mobile and desktop devices. 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 switch modes, select the Menu button. When you switch, the current calculation is cleared, but History and Memory are saved.
Save numbers to memory in Standard, Scientific, and Programmer modes. History stores all equations calculated since you opened the app.
Calculator has keyboard shortcuts to make things easier when working at a desktop PC. For example, press @ to calculate a square root, or press Ctrl + L to clear the memory.
