Why is it that (at least here) people like to write the number, then put the numeral in brackets after. For instance, I might write in this post that "It took just two (2) hours to get my car fixed today". But I wouldn't, because what would be the point?
I understand the rule that small numbers are spelled out, while large numbers should be expressed in figures. But why on earth do both? Hedging one's grammatical bets? I heard once it was about catering for those unfortunate not to be able to read - at least they'd be able to see the numbers. Great, that's really helpful for the illiterate. To know how exactly many, but not of what.
So if you see posters around town, defaced, with the numeral scratched out but the number word left intact, you might know who's responsible...
