About Logic 101

You thought logic would be easier than math. Now you're doing derivations and it's too late to drop the course. This app is for you.

- Checks the syntax of symbolic sentences.
- Tests whether the derivation is complete.
- Derivable lines are coloured blue; hypotheses are coloured green.
- Provides an annotation of the derivation, showing line justifications.
- Annotated derivations can be emailed as RTF files.
