DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+5%2A4+%29%29%2F%282-4%5E2%29+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+5+%29\",\"highlight_red%28+4+%29\"
It becomes \"highlight_green%28+5+%29%2Ahighlight_green%28+4+%29%2F%282-4%5E2%29\".
\n" ); document.write( "
Look at \"highlight_red%28+5+%29%2Ahighlight_red%28+4+%29%2F%282-4%5E2%29\".
Multiplied numerator integers
It becomes \"highlight_green%28+20+%29%2F%282-4%5E2%29\".
\n" ); document.write( "
Look at \"highlight_red%28+20%2F%282-4%5E2%29+%29\".
Removed extra sign in front of \"-1.42857142857143\"
It becomes \"-highlight_green%28+1.42857142857143+%29\".
Result: \"-1.42857142857143\"
