What is the precedence wrt Mathematica infix operators

Hello Mathematica UG:

I cannot find operator precedence documented anywhere. With the
operators from Fortran (in the old days) this was always clear, i.e
'/' before '-'.

I have been reading some code in the Trott Guidebooks which has
constructions like 'Head @@ face[[i]] / order'. I can guess that Part
has precedence in this expression, but what about Apply vs. Times?

Looking at the OutputForm shows that Apply has precendence. But,...

- Is this documented somewhere?
- Do all Mathematica operators take precedence over arithmetic operators?

TIA.

Regards..
