This lecture explains our third logical operation: conjunction.
Takeaway Points
- A conjunction joins two sentences together using a ^ symbol.
- Conjunctions are true if both of their component parts are true.
- The most common English way to express a conjunction is using “and” to separate two ideas. However, “as well as,” “in addition to,” “but,” and “yet” work the same way. Usually, “but” and “yet” express two contrasting points, but they ultimately mean that both parts of the sentence are true. (For example, the previous sentence used “but” to string two two true items together.)
- Be careful with the order of operations with compound sentences. (P ^ Q) v R is not the same as P ^ (Q v R).
