Now translate this tree into functional notation.
15
sum()
16
sum(difference(), 4)
17
sum(difference(9, quotient()), 4)
18
sum(difference(9, quotient(product(), 15)), 4)
19
sum(difference(9, quotient(product(6, sum()),
15)), 4)
20
sum(difference(9, quotient(product(6, sum(2, 3)),
15)), 4)
21
sum(difference(9, quotient(product(6, sum(2, 3)),
15)), 4)
22
sum(difference(9, quotient(product(6, sum(2, 3)),
15)), 4)
Scheme implementation
( (- 9 (/ ( 6 ( 2 3)) 15)) 4)
