123除以123又123/332+(2/333+4/333*......+332/333)-(1/333+......+331/333)
=123/[123+123/332]+[2/333-1/333]+[4/333-3/333]+...+[332/333-331/333]
=123/[123(1+1/332]+[1/333]*166
=1/[333/332]+166/333
=332/333+166/333
=[332+166]/333
=498/333
=166/111
=123/[123+123/332]+[2/333-1/333]+[4/333-3/333]+...+[332/333-331/333]

=1/[333/332]+166/333
=332/333+166/333
=[332+166]/333
