Jim is currently an IT Consultant and Math/English Teacher in the UK. Check out his interview below!

Q: What’s one fun fact about yourself?
A: I recently got back from living in Japan and played in a rock band while I was there.

Q: How did you get interested in Expii?
A: The Ramanujan problems were linked on a puzzle forum I read, and then I was hooked!

Q: How do you use Expii?
A: At first I just enjoyed the puzzles, but now I find there are lots of resources relevant to my teaching. I’m getting into contributing content, too. It’s a nifty site.

Q: What’s your math background?
A: I studied Pure Mathematics at university and ran a weekly puzzle blog while I was there. I graduated and taught the subject at high school for a few years. Now I use Math in my work and continue to teach. A running theme has always been my love of puzzles.

Q: Do you have a favorite math concept or area?
A: My favourite concept is, without a doubt, Cantor’s diagonal slash argument. I wrote my second year thesis on Alan Turing’s proof of the “Halting problem”, which involves the diagonal slash in a particularly satisfying fashion. As for my favourite area, it has to be Combinatorics. I enjoy the abstract techniques we can use for counting things, and especially how they apply to computer program efficiency – it still makes me grin that we can look at how a program is written and “count” the loops ahead of time to get an idea of how quickly (or slowly) it will run.

Q: Anything else you want to share about yourself?
A: I like making online puzzle games. My most popular so far is “Don’t Make a Box”: …perhaps because it is very simple, but it also has an elegant Mathematical solution, if you stop and think about it. The feedback I have had has been awesome, and keeps me producing more content. Last year I also finished archiving my top 50 Mathematics puzzles at Some of them are well known, some of them are not well known, and some are completely new.
