|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.
1.4.15 refer to Example 4.1(1) this should be Example
|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).
|Solution to Question 1 of
Exercises 1.5. The penultimate connective in the solution
should also be a conjunction.
|Exercises 2.2, Question 13.
The final symbol in the equation should be an x not a y.
|Question 4 of Exercises 3.1. The notation

3.1.4. In fact, you need to refer to Example 3.1.19. The
