NOTE: the order in which rule lines are cited is important for multi-line rules. For example, in an application of conditional elimination with citation "j,k →E", line j must be the conditional, and line k must be its antecedent, even if line k actually precedes line j in the proof.

A) Instructions The following buttons do the following things: Apart from premises and assumptions, each line has a cell immediately to its right for entering the justifcation. Click on it to enter the justification as, e.g. “&I 1,2”. Hopefully it is otherwise more or less obvious how to use it.

Conditional Proof The derivations we've constructed begin with premises, and derive subsequent lines using the rules of inference and the equivalence rules. In this section and the next, we'll learn how to introduce assumptions into a derivation, and to use those assumptions in …

The rule, Conditional Proof (CP) is used when we want to derive a conditional. We begin using the rule by introducing an assumption, which is the antecedent of the conditional we wish to derive. We then proceed "normally", that is, using our rules of inference and equivalence

To indicate an assumption is being made, we do two things: 1) Indent the assumed line,or, if the website you’re working on won’t save the indentation, place a vertical line, |, in front the lines that are subject to the assumption, and 2) justify it by the notation “ACP,” which means “Assumption for a Conditional Proof.” 1. R ⊃ (M v B)

Conditional Proof (CP) proceeds by letting you make an assumption, which is like saying to yourself, “OK, so what if it does rain, what will happen?,” as long as at the end of your musings from this assumption, you remember to sum it all up with a reference back to the fact that you began from that assumption. Here, you’d say:
