Well, for one thing, + can do both numeric and pointer arithmetic. Very
different things. - also means unary negation (+ also has a unary form
but it is a no-op), and as well as being useful for both pointer
arithmetic _and_ computing the difference between two pointers (a
variant of pointer arithmetic where both operands are compatible
pointers). * is also used for dereferencing pointers. And do so on.
