Modus Ponens – How the Rule Works

A quick, clear walkthrough of the inference rule Modus Ponens with examples. You’ll see how this inference rule works in propositional logic, how to read an if–then statement (i.e., a conditional statement), how Modus Ponens functions inside a logic proof, and how to avoid a common mistake in logic proofs.

This guide shows the pattern, what it means, and how to use it in a symbolic proof.
