I'm doing some LISP programming with Scheme, and I'm having trouble with converting normal mathematical notation to Cambridge notation and vice versa. Here are some samples of what I'm doing... a+c[d-e, f]*g[h] <== normal to cambridge (- (* (a b) (c d) (e f)) (+ (g h) (i j))) <== cambridge to normal if anyone could help me out that would be awesome
