    Are you asking what is .. 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 ?

    362,880

    or are you actually asking what is ...

    1x2 + 1x3 + 1x4 + 1x5 + 1x6 + 1x7 + 1x8 + 1x9 +

    2x3 + 2x4 + 2x5 etc etc +

    3x4 + 3x5 + 3x6 etc etc .. through to 9

    and then

    + 1x2x3 + 1x2x4 .......

    + 2x3x4 + 2x3x5 ...... all the way through to 7x8x9

    and then

    + 1x2x3x4 + 1x2x3x5 + 1x2x3x6

    and so on and on and on to 1x2x3x4x5x6x7x8x9 ??

    ie .. EVERY DIFFERENT COMBINATION OF 1 2 3 4 5 6 7 8 9

    This is badly stated. What do you mean by "all products" exactly? There is a large number of products which can be derived from those figures.
