Title: Maths on the Back of an Envelope 

Presenter:  Rob Eastaway

Summary: The convenience and speed of calculators has led us to believe that a number is only right when it is quoted to several decimal places. But maths is not always about getting precisely the right answer - and often a rough answer can offer more insights. This session looks at the perils of precision and the art of everyday estimation. From working out the chance of unusual coincidences, to a quick method for answering a vintage Who wants to be a Millionaire? question, Rob explores the rich topic of maths that can be done on the back of an envelope.
