Nobody said it had to be Common Lisp. I'm going by the notation the grandparent commenter used. My point was that indentation can clarify the structure of nested sexps vs putting them on one line. And that is actually what people do. "mod" vs "%" hasn't the least to do with it. This isn't even really about arithmetic; those are just at-hand examples the GP commenter chose. Could just as well have been
(foo
(bar
(baz (bax x 2)
"hello")
"world")
"!")
>the brackets you and the parent used in the s-expr are around the wrong groups of symbols
No they're not. Yours is wrong. Multiplication has higher priority than addition so the order of evaluation begins with (x * 2) not (1 + x).

FWIW, modulus has the same operator precedence as multiplication and division. So really, it is more like: (- (+ 1 (* x 2)) (mod 3 x)) or using the increment function: (- (1+ (* x 2)) (mod 3 x))
