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
Roses are red,
Violets are blue.

but this one doesn't

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 ?

Good luck.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

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
