Order the following numbers from least to greatest:

  • NUM[2] NUM[2]

SORTER.init( "sortable" )

Drag the numbers left and right so they are in order from least to greatest
SORTER.getContent()
return guess.join( "," ) === NUMS_SORT_TEX;
SORTER.setContent( guess );

Convert each number to a decimal.

\begin{align*} NUM[4] || NUM[2] & NUM[3] \\ \end{align*}

Sort the decimals: NUMS_SORT_DECS.

Convert back: \Large{NUMS_SORT_TEX}.
