CP and Cushing take the National Numeracy Challenge
Cushing was injured in a serious maths accident recently (he fell out of the bath) so I wanted to assess the damage to his number-wrangling faculties.
Fortunately, there’s the National Numeracy Challenge, which begins with a test to pinpoint your weak areas. National Numeracy is a charity that wants every adult in the UK to “reach a level of numeracy skills that allow them to meet their full potential.” Well, if there’s one thing we’ve got, it’s bags of potential.
So I called David up and we took the test together. Because I had my fears about how it might go, I recorded our conversation. You can listen to that below. You’ll probably get the most out of it if you follow along with the test yourself, by going to nnchallenge.org.uk and signing up. It only takes a minute!
WARNING: Spoilers ahead
We got to Level 2! And it turns out it did give us certificates!

All Squared, Number 11 – Maths Jam
MathsJam is an annual conference in the UK, and a monthly night in pubs around the world, organised respectively by mathematician and juggler Colin Wright, and stand-up mathematician Matt Parker. We cornered Matt and Colin at the MathsJam conference last November, and talked to them for just over half an hour about the conference, the pub nights, and a disturbing amount about cake.
Here are some links to the things we talked about:
