\n" ); document.write( "There's no better explanation than putting it into equation:
\n" ); document.write( "Let \"x\"= the number
\n" ); document.write( "\"%28-x%29\"=opposite the number
\n" ); document.write( "\"1%2F%28-x%29\" = reciprocal of the opposite
\n" ); document.write( "Condition:
\n" ); document.write( "Opposite the number times the reciprocal of the opposite = 1:
\n" ); document.write( "\"%28-x%29%281%2F%28-x%29%29=1\"
\n" ); document.write( "\"%28cross%28-x%291%29%281%2Fcross%28-x%291%29=1\"
\n" ); document.write( "\"%28-1%29%28-1%29=1\"
\n" ); document.write( "\"1=1\"
