DETAILED EXPLANATION

\n" ); document.write( "
Look at \"-2%2An-highlight_red%28+%289-10%2An%29+%29\".
Remove unneeded parentheses around terms \"highlight_red%28+-9+%29\",\"highlight_red%28+10%2An+%29\"
It becomes \"-2%2An-highlight_green%28+9+%29%2Bhighlight_green%28+10%2An+%29\".
\n" ); document.write( "
Look at \"-2%2An-highlight_red%28+9+%29%2B10%2An\".
Moved \"-9\" to the right of expression
It becomes \"-2%2An%2B10%2An-highlight_green%28+9+%29\".
\n" ); document.write( "
Look at \"-highlight_red%28+2%2An+%29%2Bhighlight_red%28+10%2An+%29-9\".
Eliminated similar terms \"highlight_red%28+-2%2An+%29\",\"highlight_red%28+10%2An+%29\" replacing them with \"highlight_green%28+%28-2%2B10%29%2An+%29\"
It becomes \"highlight_green%28+%28-2%2B10%29%2An+%29-9\".
\n" ); document.write( "
Look at \"%28-highlight_red%28+2+%29%2Bhighlight_red%28+10+%29%29%2An-9\".
Added fractions or integers together
It becomes \"%28highlight_green%28+8+%29%29%2An-9\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+8+%29%29%2An+%29-9\".
Remove unneeded parentheses around factor \"highlight_red%28+8+%29\"
It becomes \"highlight_green%28+8+%29%2An-9\".
Result: \"8%2An-9\"
