Math Magic

I've been missing from Blogland lately.

That's because we got a new desktop and it's taken a while to get it all functioning, (at least at a basic level).

Anyway I'm still aways from posting some pictures but in the meantime I thought I'd amaze you with what I learned today from my work colleague, Graeme.

He told me about CASTING OUT NINES.

there are many references if you ask Mr Google, here is just one of them that explains the theory of CASTING OUT NINES a lot better than I can.

My bookkeeper side came out when I found out what a great tool it is for checking calculations and it's a great day when you learn something useful.
