\n" ); document.write( "do inner part first
\n" ); document.write( "7 + 2[9 - 2(4-1)] --> 7 + 2(9 - 2 * 3) (removed brackets and replaced with parenthesis, no internal parenthesis any longer)
\n" ); document.write( "do internal multiplication next (multiplication and division have higher priority than addition and subtraction)
\n" ); document.write( "7 + 2(9 - 2 * 3) --> 7 + 2(9 - 6)
\n" ); document.write( "do internal subtraction next
\n" ); document.write( "7 + 2(9 - 6) --> 7 + 2 * 3
