  • Geoff Benson, Reading England
  • Perhaps this should have been worded as the total of the multiples of 9 up to 10 x 9. The total of the numbers in the 9 times table is actually 640. Try it!
  • Best Year 7 Maths Gruop Ever!, King Alfred's College OXON
  • We thought that the starter today was really easy because we all know the 9 times table and we saw the pattern in it :).
  • Mr Parsons, Ashcroft High
  • Ryan and Dave got this within half a minute.
  • Destwd, Bratislava
  • This starter provides opportunity to discuss place value the sum of consecutive numbers, triangular numbers, pair bonds to 9, pair bonds to 10. Not difficult to solve but provides an interesting starter for further discussion.

Hello World

You are buying a (driverless) car. One vehicle is programmed to save as many lives as possible in a collision. Another promises to prioritize the lives of its passengers. Which do you choose?

Welcome to the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions – in healthcare, transport, finance, security, what we watch, where we go even who we send to prison. So how much should we rely on them? What kind of future do we want?

Hannah Fry takes us on a tour of the good, the bad and the downright ugly of the algorithms that surround us.
