Puzzle (Puzzle is fill in box with operations)

First of all, this is not algebra,so expect blanks, not letters.
Ok, please solve this:

1_2_3_4_5_6_7_8_9=100

The _ is used as a "blank".
You can only use 3 operations
You guys are the only ones I trust, I thank you if you solve this.
By the way, MDAS should not be applied

Re: Puzzle (Puzzle is fill in box with operations)

hi Dee Jay

Welcome to the forum.

I'm assuming every blank must be replaced by an operation and you may repeat an operation provided you use no more than three.  Also, hopefully just two operations is also acceptable.

Note:  1+2+3+4+5+6+7 = 28

I'll leave the rest to you. 

Bob

ps.  If you meant just three in total, what happens to the remaining blanks ?
