o Remember that multiplication precedes addition and subtraction in 
evaluation, so many of your parenthesis pairs are unnecessary.  You 
may think they clarify things, but in my experience they obfuscate 
the meaning of a formula and mask errors.
While I agree with Brian's other points, I just wanted to comment that
normally, I find it much better to include parentheses around sums,
explicitly stating the order, rather than relying on (sometimes
differing) operator precedence rules. This also helps to group things,
and in my opinion usually makes things more clear, rather than
obfuscating anything. However, in this extreme example, I doubt it would
make much difference either way.
