Propositional Logic (4)

Rule 4: Conjunction

1. P
2. Q
3. P & Q

Examples

1. Jim is playing the piano
2. Charity is playing the piano
3. Both Jim and Charity are playing the piano

Again this is an easy rule to understand. It includes the ampersand symbol '&', read 'and'. If P is true, and Q is true, then both P and Q are true!
