[1/2 Formula]
    Work: Calculate the value of equation 2*3*5*7*11*13*17/(2004-2) .
    Question type: Mathematical calculation
    Solution:
          2*3*5*7*11*13*17/(2004-2)
        =2*3*5*7*11*13*17/2002
        =6*5*7*11*13*17/2002
        =30*7*11*13*17/2002
        =210*11*13*17/2002
        =2310*13*17/2002
        =30030*17/2002
        =510510/2002
        =255
    Answer:2*3*5*7*11*13*17/(2004-2)=255
[2/2 Formula]
    Work: Calculate the value of equation (2009*2009-2005*2005)/(2009-2005)+(2009*2009-2005*2005)/(2009+2005) .
    Question type: Mathematical calculation
    Solution:
          (2009*2009-2005*2005)/(2009-2005)+(2009*2009-2005*2005)/(2009+2005)
        =16056/(2009-2005)+(2009*2009-2005*2005)/(2009+2005)
        =16056/4+(2009*2009-2005*2005)/(2009+2005)
        =16056/4+16056/(2009+2005)
        =16056/4+16056/4014
        =4014+16056/4014
        =4014+4
        =4018
    Answer:(2009*2009-2005*2005)/(2009-2005)+(2009*2009-2005*2005)/(2009+2005)=4018
