One to Nine Equals a Hundred Quiz Puzzle

A trickier puzzle than last week; back to the normal degree of difficulty, although it’s another deceptively simple puzzle.

Take the digits one through to nine in order and, without changing their order, insert three mathematical symbols to make a sum. The result of this sum must equal 100 exactly. You can use the same symbol more than once, but each time you use the symbol that counts towards the total of three. That is, two multiplies and a subtraction is three symbols.

For example, you could have

1 x 2345 – 678 + 9 = 1676

But that does not equal 100!

As usual you can post the answers as a comment on this website, reply to the post on Facebook, or retweet or reply on Twitter @quizmastershop.
