Thank you!

Answer 2

Use your character map:
click [ start ] , [ all programs ] , [ accessories ] , [ systems tools ] , [ Character map ]

All the Greek letters are there, upper and lower case, and lower down you can find some math-explicit symbols. You can only get superscripts ¹, ², and ³ to use for exponents, so the ^ is still necessary notation for others.

Once you call up the character map, it should remain in your start menu if you use if frequently enough.

θ

For pi type '&' then 'pi' and then ';'
π

alt + 0178 , you will get ² . Use numberpad to type that numbers.
