For expressions such as  a-b+c,  or  a+b-c,  or  a-b-c,  there is also a fixed convention, but rather than saying that one of addition and subtraction is always done before the other, it says that when one has a sequence of these two operations, one works from left to right:  One starts with  a,  then adds or subtracts  b,  and finally adds or subtracts c.
