LOL - if someone else submitted this, it would have been trivial. But when you see "shenqiang" on the teaser, you start thinking about different number bases, unusual operations (e.g. modulo), number of prime factors, etc., etc. So in effect, this one was tricky!

I noticed the 3's, but missed because of a simple math error: 12-5=6 Oops.
