@martinlewis.moneysavingexpert.com When I give cash as a present, I style it as 'Bank of England Gift Vouchers'. It often gets a smile and bypasses the awkwardness.

@aproblemsquared.bsky.social Something has always bugged me in Maths.

0 / n = 0
n / n = 1
and
n / 0 = Undefined or Infinity or whatever

So what is
0 / 0 ?

Is it 0, 1, Undefined ?

Thanks
