Throughout this chapter, we require that all formulae are written in Polish notation and that the variables are among v0, v1, v2, . . . Notice that the former requirement is just another notation which does not involve brackets, and that by the Variable Substitution Theorem 2.13, the latter requirement gives us semantically equivalent formulae.
