Does anyone know a good online calculator for regression?

I have a TI-83, and we are using WEBASSIGN to do our homework, but the website seems to not like the equations. I have gone over them and rounded like I am suppose to. However, it appears that the TI-83 is auto rounding somewhere which is causing the inconsistancy on which part of the question the website does not like the answer to.

You can put your equations into the google search bar and see if it's any better. It can do quite a lot for you if you write out the equation properly.

It does graphing: Example

It even does 3D graphs: Example

Unit conversion: Example

And any arithmetic, obviously: Example

I found out what I was doing wrong. It was giving d(f) as the function but I was using x for the variable name so it was marking it wrong.

Good links tho, I will keep them for future use.
