Frivolous Parentheses (FP)

There really isn't an error, per se, with using too many parentheses. Nevertheless, students who consistently employ more parentheses than needed are demonstrating as much of a lack of understanding of the order of algebraic operations as those who use too few. Expressions such as

\begin{displaymath}\begin{array}{lll}
\ds{\left(\frac{(2x^2+3x)}{(x-1)}\right)}...
...{x^3}}
\;\;\;\mbox{or}\;\;\;
(3-x)/x^3.  \\
\end{array}. \end{displaymath}
