I did not see this one in the search and think it is a fun math challenge. Fans of the Hitchhiker's Guide to the Galaxy may know that the ultimate answer to life, the universe, and everything is 42. And that the ultimate question is "what do you get when you multiply 6 by 9" but it does not end there. There is a way for 6 times 9 to equal 42. Can you find it, thus revealing a deeper mystery of the universe?

It is a funny coincidence, and so is KlueMaster's clever reply. Very funny!

6x9 = 54 in the decimal system corresponds to 42 in a number system with BASE 13!

You could have put a cherry on the top of this one by posting it last October 10 and asked:

Of what is today the meaning?
