Windows Calculator

Windows Calculator is a software calculator developed by Microsoft and included in Windows. In its Windows 10 incarnation, it has five modes: standard, scientific, programmer, date calculation, and graphing. The standard mode includes a number pad and buttons for performing arithmetic operations. The scientific mode takes this a step further and adds exponents and trigonometric functions, and programmer mode allows the user to perform operations related to computer programming. In 2020, a graphing mode was added to the Calculator, allowing users to graph equations on a coordinate plane.

The Windows Calculator is one of a few applications that have been bundled in all versions of Windows, starting with Windows 1.0. Since then, the calculator has been upgraded with various capabilities.

In addition, the calculator has also been included with Windows Phone and Xbox One. The Microsoft Store page proclaims HoloLens support as of February 2024, but the Calculator app is not installed on HoloLens by default.
