 Example-(01) The distribution of the following product is arranged.
 \begin{flalign*}
 (x^{3}+2x^{2}+2x+1)(x^{2}-x+1)
 \end{flalign*}
 $\begin{array}{r@{} r@{} r r}
 x^3&{}+2x^2&{}+2x+ 4 \\
 \times(x^2&{}-x+1) &\\
 \cmidrule{1-3}
 \end{array}$

    Either I forgot math learned at University or I am misunderstanding the question: Multiplication versus Long Division? – user31729 Feb 28 '15 at 10:59
