SICP

I'm now readin SICP.Its not a bad book at all.
Its notation however sucks:
(+ (* 3 (+ (* 2 4) (+ 3 5))) (+ (- 10 7) 6))
There is no way i could see which empty)( places contain which operators without reading entire string piece by piece.
This wouldn't work with larger strings.

compare readibility:
(define (abs x)
  (cond ((> x 0) x)
        ((= x 0) 0)
        ((< x 0) (- x))))

function abs(x){
if(x>0){return x}
if(x=0){return 0}
if(x<0){return -x}
}
