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.
