Hello all,
I know that quite some folk have solved this one already and it doesn't look too daunting, really - except that: well I'm getting 186 and not 184 as result for F_3(100).
Is that a typo that has been missed because people have gone straight on to the grown-up stuff with Sigma_k F_k(10^3) - or should I perhaps go and study Chapter 2 of 'Basic Arithmetic for Massive Dummies'?
Any input is welcome. Cheers,
Claude

It really is 184. If you want, you can send me the pairs (A,B) that make up the sum by private message (you should have only four, and remember that A, B are positive so non-zero), and I'll tell you what is wrong.

Thanks for your quick response, jaap.
And thanks also for the offer of a PM conversation. I won't bother you just yet as I've actually only got three pairs so clearly there's something massively wrong with my approach.
Back to the drawing board then.
Cheers,
Claude

EDIT 10 minutes later: Now I get 184 with 4 couples... Forgot the simplest of basic checks. Would it be Friday today by any chance?
