Everyone should have a copy of Leary: A friendly introduction to mathematical logic, but the book will not be available in the book store until the beginning of next week. The next weeks I will lecture the 1st chapter of Leary's book. The following exercises might be solved during the lectures: 1.3.1 (page 15): ex. 2, ex. 3. 1.4.1 (page 20): ex. 3, ex. 4, ex. 5.1.6.1 (page 30): ex. 2, ex. 3, ex. 5. 1.7.1 (page 38): ex. 2, ex. 7. 1.8.1 (page 42): ex. 6. 1.9.1 (page 44): ex. 1, ex. 2, ex. 4.
