    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!

Where do you teach?

I teach in my home in Abbotsbury Road, Weymouth.

It's a 15-minute walk from Weymouth station, and it's on bus routes 3, 8 and X53. On-road parking is available nearby.
