DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+%284%2F15%29+%29-%287%2F15%29\".
Remove unneeded parentheses around terms \"highlight_red%28+4%2F15+%29\"
It becomes \"highlight_green%28+4%2F15+%29-%287%2F15%29\".
\n" ); document.write( "
Look at \"4%2F15-highlight_red%28+%287%2F15%29+%29\".
Remove unneeded parentheses around terms \"highlight_red%28+-7%2F15+%29\"
It becomes \"4%2F15-highlight_green%28+7%2F15+%29\".
\n" ); document.write( "
Look at \"highlight_red%28+4%2F15+%29-highlight_red%28+7%2F15+%29\".
Added fractions or integers together
It becomes \"-highlight_green%28+3%2F15+%29\".
\n" ); document.write( "
Look at \"-highlight_red%28+3+%29%2Fhighlight_red%28+15+%29\".
Factors 3 and 15 have greatest common factor (GCF) of 3. Reducing fraction.
It becomes \"-highlight_green%28+1+%29%2Fhighlight_green%28+5+%29\".
Result: \"-1%2F5\"
