Rob Eastaway

Rob Eastaway is a British mathematician, author, and speaker who is one of the country's leading popularisers of mathematics. He has written numerous books making maths accessible, practical, and entertaining for general audiences. Maths on the Back of an Envelope celebrates the lost art of rough-and-ready mental calculation, showing how quick estimates and back-of-envelope calculations can help you make sense of numbers in everyday life — from checking a restaurant bill to understanding statistics in the news. Eastaway makes mental arithmetic both useful and fun. The audiobook, narrated by Eastaway himself, brings his natural enthusiasm and clarity to the subject. Both versions offer listeners and readers a practical, entertaining guide to thinking with numbers. Eastaway's work appeals to anyone who wants to feel more confident with maths in daily life.
