Of course there's no such things as imaginary numbers... they're not real.

Anything divided by zero is "undefined".

GU5

So how about this one?

1/9 = 0.111111111111111111111111111111111111111111111111
2/9 = 0.222222222222222222222222222222222222222222222222
3/9 = 0.333333333333333333333333333333333333333333333333

etc
BUT 9/9 = 1

Hanslow

Because 9 is a magic number Add all the digits of a 'real' multiple of 9 and they'll add up to a multiple of 9.

What's the answer to 0/0?

I was always told that 0 divided by anything is 0.
But also anything divided by 0 is undefined.
But if you cancel 0s you get 1

This thread reminds me of a control theory lecture at uni where we were told an answer tended to 1 because you cancel out infinity in numerator and denominator.

A silence descended and after a short while the lecturer conceded it was "not mathematically rigorous".

I was thinking about what you said. Is 1,000,000,000 any closer to infinity than 10? I don't think it is.

carl

Oddly enough, though, ln(0) is minus infinity, because e^(-infinity)=0

And the first year in the first millennium was numberd 1. So why did we welcome the new one on 1st Jan 2000?

Because Dennis the Greek who instituted the modern Western Calendar was a numpty. He should have started it in year zero and has caused untold wrangling over the centuries because everyone knows centuries should turn at "00"
