Lost Ninth


When my younger daughter came home from her AS-level Decision Mathematics 1 exam last week, she said it was a lot harder than she was expecting it to be. She had high hopes for good marks before she went in, but there was one question worth a ninth of the marks for the whole paper that she really struggled with and couldn't answer.

It turns out, no-one else could answer it either: it was an impossible question.

Mathematicians: great at reading proofs, not so great at proof-reading.
