Response To:[Late] Friday Puzzler-- addition ()
* I'm not sure if this needs to be stated. If you find a solution with some digit used more than once (other than 000 + 000 = 000!), post that as well.
Answering my own question here, I think I have worked out that there is exactly one solution other than the trivial all-zeros one, and in it, the three letters stand for distinct numerals.
This one can be solved without trial and error.
