It's funny how Hilary and Kevin are so similar in brain power but aren't friends. Instead they compete all the time.

But they make a good team when I get them to work together. They spent this afternoon calculating tables of Fibonacci and Lucas numbers and their prime factorisations. 'Just to help Duk San,' Hilary said.

I had the feeling that it would be a bit beneath them if it wasn't for a certain morbid fascination they have with the material. They're learning both series off by heart. Apparently some of the information is useful when performing lightning mental calculations. Beat the calculator and all that.

They'll be learning log tables next.
