Description
Demonstrating accessible and useful arithmetical techniques to, roughly, calculate anything. Refresh your mental maths and learn useful short cuts, such as 'the rule of 72', to tackle everyday problems. From on-the-go shopping bills, metric to imperial conversions, and working out probability, to queuing times, currency conversions, and more. Then test your thinking with a series of questions inspired by the informed estimations of physicist Enrico Fermi: from how many hairs on the average adult head, to are you descended from Richard III? Free yourself from calculators and be liberated by the power of educated guesswork as a better guide to getting to the bottom of things.
