Everyone makes mistakes in maths — and that’s a good thing! Mistakes help us understand what really works and what doesn’t.
The more mistakes you see, the easier they become to spot. And once you can spot them, you’re much less likely to make them yourself.
In this session, we will sharpen our mistake-detecting skills by looking at a collection of fake proofs: arguments that look convincing at first glance, but hide a sneaky error somewhere inside. Your job is to find where things go wrong and explain why.
