This is a short introductory maths text covering the essential concepts and techniques which first and second year geology undergraduates must learn. It starts with a revision of basic algebra and ends with a chapter each on simple differentiation and integration, and includes a chapter on introductory statistics. It adopts a gentle pace and uses geological examples throughout. There are lots of worked examples and end-of-chapter questions, with answers. This book should be of interest to undergraduates in geology and earth science; some environmental science programmes; and courses on techniques in geology.
