perplexus.info :: Numbers : Plus and Minus

Plus and Minus (Posted on 2003-02-05)

Frame at least 8 different equations by inserting plus and minus signs only into 1,2,3,4,5,6,7,8,9; to give a total of 100.

For example: 123 - 45 - 67 + 89 = 100

(The numbers must stay in the normal ascending order from 1 to 9).
