You can express any number as the product of its constituent digits and its corresponding place value. Below are a few examples.

\[\begin{align}

& 8={{10}^{0}}\times 8 \\

& =\text{eight} \\

& 18={{10}^{1}}\times 1+{{10}^{0}}\times 8 \\

& =\text{eighteen} \\

& 180={{10}^{2}}\times 1+{{10}^{1}}\times 8+{{10}^{0}}\times 0 \\

& =\text{one hundred and eight}

\end{align}\]
