    Default Alt Code in Windows 10

    I want to type the square root symbol, Google search says ALT + 251 but it doesn't work in my Win10 PCs

    Any suggestions?

    I think you use the numeric keypad. But I didn't get a square root symbol.
    251 =
    0251 =

    I normally google for it: and past it in: √

    Works in Word. Will work but W10 is not a text editor.

    Depends on the app you are using, heres word --- Click where want, press Alt + 251 Press enter.

    you can run the character map app and cut and paste, been in windows forever but it takes a bit of searching, this symbol is called square root and hovering over it shows U+221A whatever that means √√√√√√√√√√√√√√
    it's about 4 clicks up from the bottom in the scroll bar

    edit: just figured out if you tick advanced view there's a search box you can search for square root and find it that way

    To insert Square root symbol (√) in Word, type 221A (Select them) and then press Alt+X to convert the alt code into a square root symbol (√).

    Several Methods as well https://www.solveyourtech.com/how-to...ymbol-in-word/

    Method 1 works in Word

    NOTE: Any tests have been with Word in Office 365. Office 2013 is to outdated and dont have any installed.

    Tested on Office 2010 and 2013 old test VMs, I get the square root symbol as well.

    My stock Android keyboard has a square root key buried deep in the symbols board
