[EMAIL PROTECTED] gives a UBASIC solution to Steinar's problem:
<<
> First, perhaps I should explain some notation :-) a_11 is the letter `a',
> followed by 11 in subscript. x^2 is the letter `x', followed by the letter
> 2 in superscript (ie. `x^2' would be mathematically the same as `x*x').
> OK, here goes:
>
> If (3x^2 - x - 2)^6 = (a_12)x^12 + (a_11)x^11 + ... + (a_1)x + a_0, what
> is a_0 + a_2 + a_4 + ... + a_12?
>
> The answer is an integer from 0 to 999, inclusive.
