You opened the door : the temperature in the room where I'm typing this right now is less than 300K (it is ~295K).
Now let's get you to define "number", wot ?

sorry.. i mistyped... of course i meant either less than 300' C or less than 0K...
Will try to answer on what i'm critized on right now...
My definition on number (in this context) is a quantity... It can be anything quantitive including lengths and other such stuff...
My first reason to think that 0 was not a "number" was that I saw it as much number as infinity... It is sort of like that the numbers 0,0000...1 to 10^9999... are possible to exist in a totally different way than zero an infinity...
Its like that zero is infinitely small while infinity is infintely big..,,
And the stuff with that you cant divide with zero, is that you can divide by all other "numbers"... so the fact that you cant divide vy zero makes it somewaht differant from other numbers...
