DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+2%2Ax%5E2+%29%29%2A%28y%2Bz%29+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+2+%29\",\"highlight_red%28+x%5E2+%29\"
It becomes \"highlight_green%28+2+%29%2Ahighlight_green%28+x%5E2+%29%2A%28y%2Bz%29\".
\n" ); document.write( "
Look at \"2%2Ahighlight_red%28+x+%29%5E2%2A%28y%2Bz%29\".
Replaced x with 2
It becomes \"2%2Ahighlight_green%28+2+%29%5E2%2A%28y%2Bz%29\".
\n" ); document.write( "
Look at \"2%2Ahighlight_red%28+2+%29%5Ehighlight_red%28+2+%29%2A%28y%2Bz%29\".
Replace constants in factor: \"highlight_red%28+2+%29\",\"highlight_red%28+2+%29\" with \"highlight_green%28+4+%29\"
It becomes \"2%2Ahighlight_green%28+4+%29%2A%28y%2Bz%29\".
\n" ); document.write( "
Look at \"2%2A4%2A%28highlight_red%28+y+%29%2Bz%29\".
Replaced y with 3
It becomes \"2%2A4%2A%28highlight_green%28+3+%29%2Bz%29\".
\n" ); document.write( "
Look at \"2%2A4%2A%283%2Bhighlight_red%28+z+%29%29\".
Replaced z with 4
It becomes \"2%2A4%2A%283%2Bhighlight_green%28+4+%29%29\".
\n" ); document.write( "
Look at \"2%2A4%2A%28highlight_red%28+3+%29%2Bhighlight_red%28+4+%29%29\".
Added fractions or integers together
It becomes \"2%2A4%2A%28highlight_green%28+7+%29%29\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2A4%2A%28highlight_red%28+7+%29%29+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+7+%29\"
It becomes \"2%2A4%2Ahighlight_green%28+7+%29\".
\n" ); document.write( "
Look at \"highlight_red%28+2+%29%2Ahighlight_red%28+4+%29%2Ahighlight_red%28+7+%29\".
Multiplied numerator integers
It becomes \"highlight_green%28+56+%29\".
Result: \"56\"
