I am facing problems while writing degree symbol in my laptop.I am doing a research project where it needs the most. Can anyone help me about this? 

one site shows - Press and hold the ALT key  and type 0176 on the numeric keypad of your keyboard having NUMLOCK on. If you have a Laptop and there is no numeric keypad, press and hold the Fn key before typing the 0176 numbers of degree symbol
