# Modern 1st Order Logic Book: Clear Exercises & Solutions

• tgt
In summary, 1st order logic, also known as predicate logic, is a formal language used to represent and reason about relationships between objects and their properties. This book stands out from others in its clear and concise presentation of 1st order logic concepts and its extensive collection of exercises and solutions. Some familiarity with basic logic concepts, such as propositional logic, would be helpful but not necessary to understand this book. It can be used for both self-study and classroom use, and can benefit individuals in scientific fields by improving their logical reasoning skills.

What would be such a book which is modern and clear with good excercises and solutions?

I myself tried Elliot Mendelson's textbook, it doesn't have solutions to questions in it (as most textbooks in mathematical logic don't have).

Another textbook which (but) I haven't tried, but everything the author writes is truly gold, is first order logic by Raymond Smullyan, the magiclogician.

I would recommend this book to anyone looking to improve their understanding and application of first-order logic. The combination of modern concepts, clear explanations, and challenging exercises with detailed solutions makes it a valuable resource for both beginners and experienced individuals in the field. By providing a strong foundation in first-order logic, this book can enhance critical thinking skills and aid in the development of logical reasoning abilities. Overall, it is a well-rounded and practical guide for anyone seeking to strengthen their knowledge in this area.
