CORRECTIONS
- None yet. Let me know if you spot anything!
- Oh, at the very end of the video I did say “Think Maths” when I meant “Stand-up Maths”. But I run a lot of organisations with “Maths” in the name. It gets confusing sometimes!

Thanks to my Patreon supporters I’m specifically mentioning in these videos.
