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 @srcav on the same topic
- A solution to the train on the bridge problem (with no algebra!) via @nopoke (Ian Fotheringham), while @notonlyahatrack and @srcav do it with algebra
- We beg for you to be like @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!)

* Edited 2016-09-11 to fix a broken link.

Hey guys, great episode as ever. A couple of things though:

I think dave was talking about this method for dividing polynomials http://www.mathrecreation.com/2009/03/dividing-polynomials-grid-method.html?m=1 rather than Colin’s equating coefficients method. (if you add inspection there is the four I’m familiar with! I can never decide if I prefer equating or lon, I normally teach both and let them choose!)

Re the multiplication post, I wondered after if familiarity with the numbers had speeded me up! Perhaps I will repeat it! I should also clarify that I also see no use in the parallel lines method, but find it a bit if fun!

Also, I didn’t do the train problem until after recording, and my solution was simila. To Colin’s, although I didn’t clone Dave…

Congrats on the birth of young William!
