DERP

(define (A x y)
(cond ((= y 0) 0)
((= x 0) (* 2 y))
((= y 1) 2)
(else (A (- x 1)
(A x (- y 1))))))
I understand everything up until the else.
HALP.

>>12
Wait a second >>10
Would (A x(- y 1)) run before (A (- x 1)) and use it's value as the argument? I would think (A (- x 1)) would run first and use it's value for the argument of (A x(- y 1)) .
