It's almost as if it's been designed by someone who has seen a calculator, but doesn't actually understand anything about what it does.
Oh, wait ...

I love the way there are three ways to do 'sin' and two to do 'sin x'.
And my calculator is severely deficient in not having a 'cog+' button.
Come to think of it, many calculators have two different 'minus' keys, so having two decimal point buttons is perfectly reasonable!

How would the meaning of the question be any different if they left out the word "mathematically"?

Me too!
I knew I had blogged about this a while back. Didn't realise it was over a dozen years ago!

What a lovely article - and a fitting way to sign off.
All the best for the future, and congratulations for everything you have achieved.

Bank of England inflation website gives a general inflation multiplier of 2.89 for the same period.
(So fees of £3000 in 1986 would be 3000 x 2.89 = £8670 in 2024.)
Is there a reason for the massive discrepancy?
(Genuine question. I don't want to misrepresent this, but don't understand it!)

[Obvs, not all A-level students realised this. I recall a student who used to copy out the mark scheme from past papers and hand it in. Even including 'oe' as part of his answers! I explained how pointless it was for me to mark the mark-scheme, but that didn't deter him. He got a U.]

Have I just got a naive/rose-tinted view of how things were pre-AI? Or do we just need to convince pupils that the same is true with AI?

Hi @atmmathematics.bsky.social
What's the state of play regarding ATM and the formation of AMiE?

Nice to see the word "puzzles" is plural here.
Looking forward to more of them!

Your question seems to me to be a 3D(-ish) version of this.
On a globe, draw the circumference of the earth that is equidistant from Boston and Miami. Then repeat for the other pairs of cities.
Make a Voronoi-type diag, then transfer this to a map.
I reckon your version is plausible.
Any use?
