Sorry if my question is too noobish, but I can't get the square root symbol in my desktop pc using ALT + 251. When I type that key combination, it gives me ¹ instead. I have searched the internet, but I can't find any solution.
Probably relevant: I live in Colombia and just purchased this low budget second hand desktop. My keyboard language is Spanish(Colombia)
Operating system: Windows 8.1 Pro.
