I know we have math characters at this site, but not a fantastic collection, but here are some math characters you can copy and paste whenever you are writing down equations.

√ 
α β γ δ ε η θ λ μ ν ξ π ρ σ τ υ φ χ ψ ω Δ Λ Ψ Ω
∂ ∑ ∞ ∫ ≈ ≠ ≡ ≤ ≥ < > ћ

I know we have many of these characters, but notice the squared and cubed sign, the plus-minus sign - hbar is also in there. This small change can make equations look so much more delightful:

without

(I might write) G(∫ ∏_(n=1)^3 E^2/c^2 - |p^2| = Gd^3v^2(\hbar (c/G))d^3t

Using those added symbols, it looks quite a bit better (note, the dots are just lining in the upper and lowercase numbers (n=1) and 3 (space dimesions:)

......3
G(∫ ∏ E/c-|p|)=Gdv(ћ(c/G))dt
.....n=1

It makes it much more cleaner to read. So they are there if you need them.

I think it is not difficult to implement a LaTeX server for mathematics symbols. But the problem with that is that only arithmetic savy folks would know the code for the symbols. It's like a programming language.

I have my keyboard on US International setting, and then some things are even easier Dave.
ALT GR + 1 =
ALT GR + 2 =
ALT GR + 3 =
ALT GR + 4 =
ALT GR + 5 =
ALT GR + 6 =
ALT GR + 7 =
ALT GR + 8 =
ALT GR + 9 =
ALT GR + 0 =
ALT GR + - =
ALT GR + = =
ALT GR + m =
ALT GR + c =
ALT GR + s =
ALT GR + l =
ALT GR + d =
ALT GR + r =
ALT GR + t =
ALT GR + [ =
ALT GR + ] =
ALT GR + / =

Furthermore, with your Numpad ASCII, leading zeros aren't necessary:
= 7
→ = 26
← = 27
= 246
= 241

I have added a few more symbols:


which covers most of the requests. Some kind of latex compiler would be nice but would involve generating images, and it would get fairly complex.

~   Alt + 0126
{   Alt + 0123
}   Alt + 0125

True Nizzle, the leading zero is not required in NSF (but is required in Word).
Hi Dave what you are trying to discover ?

Very useful but is there a subscript 2 anywhere out there?

As in C02?

The purpose and meaning of Life? :-\

The meaning of life, is to simply live it.

Yes
If you type
Code: [Select]
CO[sub]2[/sub] you'll get CO2

There is the same for superscript, but then you have to use
Code: [Select]
[sup] and [/sup] tags
