@themathsbazaar I'm of the opinion that a calculator is useful for the basics (think the ones usable for GCSE). Anything more and it's time for jupyter-lab, numpy, scipy, sympy and their friends. In the real world who uses such a calculator?

@AdeleBatesZ @Dorastar1 @EyesShutTeacher I actually admire the style. Yes, I know we're not *supposed* to, but underneath it all there is a tacit acknowledgement of respect and, dare I say it, *trust*.

@PeterOnion The pressure gauges are especially useful.

@thepetitioner @Sue_Cowley Strongly agree! I got my second degree in (mostly) maths and its learning. Turns out that at degree level they don't ask you what 6×7 is! That's what I have a laptop for. For professional work I have access to a mahooosive data centre.

@Sue_Cowley I volunteer in a school but work in the high-tech industry. In industry when things don't work out we talk about “root cause analysis” a formal way of saying “fix the problem, not the symptoms”. This takes time but pays off in the long term. See, e.g., en.wikipedia.org/wiki/Five_whys

@emfcamp Looks like all the tee-shirts are sold out (I only just spotted this). Any chance of a second batch being released?

@joneringram It was great to watch him work. We also had an interesting discussion as to why we need to get rid of subtraction and division as well as another about fractional roots. Good times!

@DrBradJohnson I didn't realise this was specific to teaching and thought it applied to all management roles. Turns out it does!

@AdeleBatesZ Yeap, had that one today. May I add a good night's sleep as well?

@CityJuiceBar Now, the *real* geeks amongst us will recognise that this *isn't* 8 hole ASCII but something far more exciting. What is it and what does it say?

@IamHappyToast After careful consideration I've decided that I will not be part of that ad revenue. Furthermore, I will no longer be part of their Prime revenue either.

@alexellisuk OK, that's a serious beast system. My guess is that it'd cost a fair amount but deliver handsomely.

@BenRogersEdu @OpenUniversity “You can't hold it in your head until you've held it in your hand.” We can talk about concrete and manipulatives but it's how the learned interacts with them that's the key thing. Me? I can't keep from playing with things!
