The salon I used to go to offers a 10% student discount. Every time I went up to pay, the woman had to use a calculator and the most roundabout formula imaginable to figure out what's 10% of £30.
Oh no, I'm going to be outed, but just cannot resist out-geeking Peter Hall, of the Association of Teachers of Mathematics by pointing out that you if you want to decide which number is _smaller_ you _do_ ignore the minus sign.
To be clear Duncan, the debate wasn't which was the smallest but which was the lower temperature:
_"On one of my cards it said I had to find temperatures lower than -8. The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn't"_
Even THE WOMAN IN THE SHOP got it wrong.
*I just found it amusing that the maths teacher got muddled and said smaller when he shouldn't have.*
I've been puzzling about this for nearly three days, because it is a pretty simple error, especially for someone whose job it is to clarify this sort of thing.
Then I realised. Whilst it might have been **said** by a maths teacher, it was **written down** by a reporter from a local newspaper. His name probably isn't even Peter Hall.

Sigh I feel twenty years old again.
I'm struggling to see where the stress is in that sentence. Are you a maths teacher, Duncan?
