This is a good resource to print out and have near your computer desk!

How do I type nicely the square and the square root and other math symbols?
(Just hold "Alt" down and type the numbers in on the right side of the keyboard (num pad) then let go off the buttons and the character will appear.)

 I have compiled a list of Math symbols that you can write easily in your documents.
Hope you like it!

The trick: "Just hold "Alt" down and type the numbers in on the right side of the keyboard (key pad) then let go of the buttons and the character will appear. "

Example: "ALT" and "253" will render ² The square symbol!
