= 2002 x 14 + 14 + 1988 + 2001 x 2002 / 2002 x 1 + 2002 x 503 + 504 x 2002     = 2002 x 14 + 2002 + 2001 x 2002 / 2002 x 1 + 2002 x 503 + 504 x 2002     = 2002 x 14 + 2002 x 1 + 2001 x 2002 / 2002 x 1 + 2002 x 503 + 504 x 2002     = 2002 x (14 + 1 + 2001) / 2002 x (1 + 503 + 504)     = 14 + 1 + 2001 / 1 + 503 + 504     = 2016/1008 = 2
