Okay, so we both mean the same thing, but put it differently.
The above 2010 + (-2008) + 2 is how I suggested it should be done (so=20
you can use the law of associativity and add a negative number) in my=20
original mail (the one you first replied to)
Maybe I could have said that + and - are usually left associative also=20
(I just said left to right)
I agree simply seeing it as the wrong operation makes sense (and then it=20
doesn't matter) but it's good to also know that + and - both have the=20
same precedence, which is what I was trying to say there.
