"Depending the precedencees instead of using parantheses is just one more way to make C unreadable."
Christoph replied:
.. religiously following that one MISRA-C rule about not placing any dependence on C operator precedence is one of the fastest ways of turning legible code into a perfect mess.

(Hint: Lots of things in C are operators - array accesses "[]", member accesses ".", member accesses from pointers "->", address-of "&", pointer dereference "*", unary plus and minus, assignments, and so on, are all operators that do have a place in the precedence table.)

OK, is this better ?
"Depending the precedencees beyond the totally obvious instead of using parantheses is just one more way to make C unreadable."

for instance
Ralph = George[(Phil +1)] - is almost abuse of ()
but
Ralph = George +7 /5 -3 *Phil; - ia abuse of 'precedence knowledge'
