DD4 would probably enjoy learning about this - she is very interested in what number everything is at the moment. I'm pretty sure that it is most likely a misunderstanding of how numbers and words relate - but anyway I think being as she's asking I might as well go with it.

Trouble is I think I did 1 day of binary (so 30 minutes) at high school 25 years ago. Being as it had no interest to my style of thought I took in nothing except it has something to do with 0's and 1's and a bit from the x files..

Anyway anyone got any suggestions as to where to start?
