I have made a expression calculator using PHP, i dont know weather to put it on my website. Would it be usefull?
PS havnt published the website yet

Making a expression calculator using PHP.
I'd find it useful. Is it similar to OpenOffice Math?
If it would be useful or not depends on what your website is about. Do people who visit your website need it? Or will it be the main attraction?
If it is any good, I say go for it.
However, I beat you to it. I made a huge calculator with a ton of built in functions already:
nixelinc.org
Programmed from scratch by a friend and I.
Check it out. Look at the publications for some examples. If you have ever used matlab or Mathematica, it is very similar.

To make a truly good one, the best thing to do would be to make it at once very powerful and versatile, while still keeping it extremely easy to use and learn to use.
Most of the command-line type calculators I've seen are either too simple; they won't do much useful, or to difficult to use: you have to learn complicated syntax for putting in problems. If you could make a simple to learn, but powerful one, you'd really have something there.

I agree that that kind of command line calculator would be great. I have used Mathematica and I find it to be extremely picky in terms of syntax. I don't know how many times I have entered something and gotten an error just because I used parenthesis instead of brackets or I didn't capitalize something.
If you can make one that is just as powerful but is less stringent in syntax that would be great.
I thought I'll be ok if your website must use calculation for Math 
It might be useful, but I think SAGE is good enough for me. But someone else might like it.
