If you click "Reduce", the system will produce a lambda term that is guaranteed to be reduction equivalent (`<~~>`) with the original term. So `((\x (\y x)) z)` reduces to (a lambda term equivalent to) `(\y z)`. -*Let*: in order to make building a more elaborate system easier, it is possible to define values using `let`. +*Let*: in order to make building a more elaborate set of terms easier, it is possible to define values using `let`.
