In Canada, a sequence of numbers is spoken as they are written:  1233 44 845. In the UK you would say the above sequence 1 2 double 3 double 4 845.

Funny how the brain is taught to process, because I find it exceedingly hard to follow. Or maybe it is because my brain always reacts with a ‘why are they saying double instead of four four?’ instead of actually processing the information.
