In most foreign languages, while the alphabets are different to the ones we are used to, the numbers always remain constant. Not so here, the numbers are entirely unrecognisable and it's a pity I can't access the web to show you an example. We'll try to take a photo of a clock or something and hope we can upload it.
This does make it a bit more difficult to get by but we can always resort to the good old fashioned and foolproof method of putting up the number of fingers. :o)
