Is there a way to get Mathematica to solve a system over the integers?

I guess I can reduce down the equations a bit, but I'm not too sure if that'll help that much.

Hm... why can't Mathematica not solve

Solve[{c, a+c^2 d, a^2+b+c d^2+c^2 e, a^2 b+ b^2+ d^2 e+c e^2, a^3+6 a b+d^3+6 c d e, a b^2+3 d e^2, b^3+e^3}=={h,f, f^2+g+h^2 t, f^2 g+g^2+h t^2, f^3+6 f g, f g^2, g^3+t^3}]

It just sits there loading! I'm trying to find the unknown variables... Is there something wrong with the syntax?

That's so cool!

I now have accomplished factoring

Okay, thanks. I also realized \[Theta] will also work...

Yes, I got the plot to work! (Yay!)

Although nothing showed up, implying I need to change the domain and range of the plot to get it to actually plot. Any ideas?

Yes.

I was using the online version of Mathematica, and I'm wondering if there is a way to delete your notebook cells...

Yes.

How do you remember all of the commands? I have no idea what "ToExpression", "ToString i" and all those random i/n means.
As much as I can guess, you're telling Mathematica to find the number of digits with 1 from 1 to 999....

But is there a way to represent v and u in terms of m and n?

For example:

So I'm wondering if it's possible to represent u,v in terms of m and n in:

Sorry that I didn't explain well enough...

Sure, that works. But I'll need to solve for u in (1).

Like... reduce the equation to another equation.
