There's a constant that is very close to an integer that's referenced here: http://xkcd.com/217/
$e^{\pi} - \pi = 19.9990999$
We nerds find this to be cool because it has two mysterious numbers and it's so close to being an integer.
Well, I got myself into a pickle here when I got curious how much we would need to offset $e$ and $\pi$ to make it come out to $20$. So I set myself up with a single constant $c$ in:
$(e+c)^{\pi+c} - (\pi+c) = 20$
And it occurs to me that I've simply been out of math too long to figure this out on my own. At the same time, I can't just 'let it go' (who does that? What the fool calls inability is what the wise man calls opportunity for growth!)
What steps would I take to solve such an equality?
Note: the tag selection didn't give me much to play with. I would prefer the tag of [Constants] but it's unavailable and alas I can't transfer my SO rep to here. :S
