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}\]
