Back at school now for two days - it feels like two weeks.
Great fun, though.
I've had a note in the homework diary which said: The square on the hypotenuse of a right (angled) triangle is equal to the sum of the squares on the adjacent sides.
Now, is this a joke? Has a nine year old boy really been taught this at home by his parents? We certainly don't cover this in school at this age. Or is this the beginning of a bizarre maths dialogue?
All kinds of follow up comments occurred to me:
E = mc squared.
Yes, indeed, sirree!
I'm glad you're sure, because I'm not!
The area of a circle is pi times r squared.
I wasn't sure, so I chickened out.
I drew one of my trademark smiley faces - adorned with curls.
Let the parent make of that what he will. It certainly produced peals of laughter from me.
