1 - 2 / 3 / 4 - 5 / 6 - 7 + 8 * 9 = 100?

Fill in the missing pairs of parenthesis to make the above equation total exactly 100. Mathematical rules apply. This is Junique's Puzzle published in the Manila Bulletin a while back.

1 - 2 / 3 / 4 - 5 / 6 - 7 + 8 * 9 = 100?

(1 x 2 + 3) x 4 x 5 + 6 - 7 - 8 + 9 = 100.

OR

1 + 2 + 3 + 4 + 5 + 6 + 7 + (8 x 9) = 100.

1 - 2 / 3 / 4 - 5 / 6 - 7 + 8 * 9 = 100?

1+2-3*4+5*6+7+8*9 = 100

1*2*3-4*5+6*7+8*9 = 100

thats the closest i could get!

1 - 2 / 3 / 4 - 5 / 6 - 7 + 8 * 9 = 100? --- i couldn't find a solution so that all the - were the same operation

/ were the same

and * were the same
