Math Input Panel

Math Input Panel is an application that is included in Windows 7 and later versions of Microsoft Windows. It allows the user to write mathematical formulas using input devices such as a mouse, touchscreen or an external digitizer.

Math Input Panel can insert mathematical formulas into programs that support the Mathematical Markup Language (MathML). MathML is supported by major office products such as OpenOffice.org, LibreOffice, Office 2007 and later, and Microsoft 365.

Math Input Panel was later made an optional feature in Windows 10 build 21332.1000 where it can be installed through the "Math Recognizer" optional feature in Settings.
