Although the number π ( pi ) is a constant widely used in mathematics, physics, and other disciplines, there is no physical or virtual keyboard key that allows you to type the symbol directly. The way you write it depends on your computer's operating system. On mobile devices, the simplest will be to use the copy and paste function.
Regardless of the version of Windows you use, press the Windows + R keys, type charmap, and press Enter. The Character Map window will appear. In Search, type pi in the box and click Search. Select it, and click the Select button. Place the cursor where you want to paste it and press Ctrl + V.
