•
• Thanks to everyone for making the comments and as a result the instruction to a calculator has been removed. It is now up to the teacher to declare whether or not a calculator can be used. This makes a worthwhile pencil and paper calculation practice but even with the of a calculator it is expected that the mental process involved in deciding which numbers are likely candidates is also worthwhile.

## 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. In Hello World she lifts the lid on their inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing. more...
