# Wrong, but Useful: Episode 9

/podcasts/wbu9.mp3

In Episode 9 of Wrong, But Useful, @reflectivemaths (Dave Gale in real life) and I (sounding a bit like a Dalek) discuss:

- MathsJam conference
- @johndavidread’s ideas on minches and mounds
- @srcav’s post on multiplication, Colin’s forthcoming post on division, and @robeastaway’s thoughts on zequals
- The TES Maths Podcast - especially worth listening to Charlie Stripp’s interview
- How Colin factorises quadratics
- Dave’s packs of cards, and why $37%$ is usually a good guess; Colin’s million-to-one shot; and Dave’s dice
- @richarddeakin’s question about vocab, and another post by [twit handle = ‘srcav’] on the same topic
- A solution to the train on the bridge problem (with no algebra!) via [twit handle = ‘nopoke’] (Ian Fotheringham), while [twit handle = ‘notonlyahatrack’] and [twit handle = ‘srcav’] do it with algebra
- We beg for you to be like [twit handle = ‘twentythree’] (Drew Barker) and leave a nice iTunes review
- Dave’s question:
*Prove that the sum of five consecutive squares is not a square* - Colin’s big announcement
- We run through some tiresome puns and encourage you to go to mathsjam.com to find a local MathsJam (or create one!)
