Sets, Logic And Maths For Computing

From the reviews: "The book covers the very basic concepts of sets, relations, functions, induction and recursion, combinatorics, probability, trees, propositional logic, and elementary concepts of predicate logic. The text is easy to read, and the concepts are presented in an understandable way using many examples. The book contains exercises with solutions, gives several further exercises, and hints for further selected reading. ... the book is recommended for undergraduates as a very first introduction to the basic ideas of finite mathematics and logic."
