Twitter is a wonderful thing.
I woke up this morning, fired up my PC, checked my twitter stream and was instantly enlightened.
A tweet from @Teach Further Maths informed me that the number 40, when written as forty, is the only number that is spelled in alphabetical order, and that “one” is the only number that is written in reverse alphabetic order. I didn’t know that before, but now I do, and that makes me happy.
Wanting to return the good deed, I replied with a tweet to let them know that four is the only number whose written form contains the same amount of letters as the number itself.
And then @Chris Smith joined in to tell the world that TWELVE is the only number whose Scrabble score matches it’s numerical value. Brilliant.
