Not if different letters represent different digits, at least in decimal.

Of course in that case, two + two = four doesn't work either...

Scholze and Stix did not even say the proof is wrong; they only had questions on a certain lemma of central importance. At least now Mochizuki seems to have tried to address those issues. (though in a not very polite way, according to Woit)

Code:
 523
+523
----
1046
How is this not a solution? It's not unique, but it works for two+two=five.

Code:
 734
+734
----
1468
similarly works for two+two=four (again not unique)

Personally, I find going through all the extra language needed to try to be interpreted as polite lowers the SNR over a serious channel.

It drives my SWMBO bonkers!!!

It is. The routine I wrote to find solutions wasn't writ right.

So I wrote another routine. This one produced 35 solutions to two + two = five and 7 solutions to two + two = four, in which different letters represent different digits.

So in Cryptarithm Land, two + two is five times as likely to be equal to five as it is to be equal to four.
