for CAlculus Rate Problem Solver

Word-maths problem language, after the fashion of STUDENT, but with a rationalised internal structure. Exemplary and underrated structural AI solution done by Eugene Charniak as a Master's Thesis. Charniak was the editor of the multivolume AI Encyclopedia

Internal pattern matching done in CONVERT, and Moses SIN used to do the final mathematics (which raises the question of why CONVERT was preferable to the internal patterning system of SIN, given the latter was purpose built to algebra, while the former was designed for maths)
