I am aware, but ignorant of the "rules" that the BBC follows. Some internal script to moderate, guideline and direct what they publish, how they publish, etc.
Then again the same can be said of any government backed, funded news agency. But I do agree alot of Islamic math is given, even to defaults such as "arabic numbers."
But this is above what I know. :) It's something I'd like to narrow down, learn and discover, but it's just quite a bit of info to take.
