Examples 1.3.5(1). An extraneous negation sign has found its way into the formula in the truth table. Erase it.  Due to printer's devil.

Examples 1.4.15 refer to Example 4.1(1) this should be Example 1.4.4(1).
Euan Aitken
Solution to Exercises 1.3 Question1(a). The truth assignment leading to F is P=T, q=F and r = T (the value for r is missing).
Aaron Molesbury
Solution to Question 1 of Exercises 1.5. The penultimate connective in the solution should also be a conjunction.
Alexander Evetts
Exercises 2.2, Question 13. The final symbol in the equation should be an x not a y.
Calum Wyness
Question 4 of Exercises 3.1. The notation used in the solution does not match that used in Example 3.1.4. In fact, you need to refer to Example 3.1.19. The first-order language of logic used has two 1-place predicate symbols A and B and two 2-place predicate symbols P and Q. The formulae have to be written in this language. The formulae you write down are then interpreted as the given relations in the family tree.
