Book talk:E.J. Lemmon/Beginning Logic

Currently chapter 2 is referred to as follows:


 * : Chapter $2$: The Propositional Calculus $2$: $3$ Truth-Tables: Exercise $6 \ \text{(ii)}$

Should this not be:


 * : Chapter $2$: The Propositional Calculus: $3$ Truth-Tables: Exercise $6 \ \text{(ii)}$

instead? &mdash; Lord_Farin (talk) 08:02, 19 August 2022 (UTC)


 * No, because chapter $2$ is called "The Propositional Calculus $2$", not "The Propositional Calculus".


 * Chapters are:
 * $1$: The Propositional Calculus $1$
 * $2$: The Propositional Calculus $2$
 * $3$: The Predicate Calculus $1$
 * $4$: The Predicate Calculus $2$


 * Confusing and messy but it is what it is. --prime mover (talk) 08:54, 19 August 2022 (UTC)


 * Alright, all clear. Thanks. &mdash; Lord_Farin (talk) 08:56, 19 August 2022 (UTC)
