Happy X-maths! (Patreon)

We're filming the SUM Xmas video today, exploring a new mathematically rigorous which I tried out with 18 other online maths humans. Many of them tried to hack it. It was chaos.

Don't forget to add your postal address to your Patreon profile if you'd like to receive an Xmas card from me. You have a few more days until we start posting them out!
