Hmmmmmm...having sorted out number places I move on to multiples and factors. Obviously I have been multiplying and dividing stuff for years but I had no idea what these things were called.
I do hope that Maths gets a bit harder than this.
Now just in case you, like me, stopped paying attention at school in about year 9, I should point out that, for example the multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96 etc, etc.
Whereas the factors of 8 are only 1, 2, 4 and 8.
So the number of multiples for any given number is infinite whereas the number of factors is finite.
All of which made me wonder (mostly because working out multiples and factors is not very stimulating) what about infinity. Surely since for 'a' to be a factor of 'b' then 'b' has to be a multiple of 'a' (note that 8 is a multiple of 1, 2, 4 and 8) does it mean therefore that infinity is the only number that has an infinite number of factors and a finite number of multiples (ie 1 - infinity). Can you even divide by infinity? If so the answer is probably infinity in which case is infinity some sort of odd (I mean that in the sense of weird) prime number?
Maybe the answer to all these questions is that infinity isn't a proper number because mathematicians are always doing silly stuff like that so that normal people can't understand what they do.
Still these and other questions lay heavy on my mind. Probably because I am a humanities graduate who doesn't really understand mathematics.
