nice teaser... it could have been better phrased though... "reverse" was not the best word for this situation...
i would be more than happy to update or approve of a correction, what do you think a better word would be?
yes, didnt kinda get the term "reverse". although there's a hint.
i guess you should have said it like,
"What is the smallest number, besides 1, that is one less than twice its digits reversed?"
what you think?

meh. Math teasers are so unappreciated.
Lol, I liked it. I like ones you can do without any paper, like this.
The hint looks like you are multiplying A and B as variables. I understood it, but some people could be confused...
Great teaser though!
