# Adding/Subtracting to 100

Posted on 2003-11-25

I need to find out a way to figure out how to figure every way to get to 100

like

1+23-45+67-8+9 (thats not equal = 100)

but stuff like that.. in order.. allowing any amount of numbers.. 1-9 in that order

so like

1+2+3

12+3

1+23

123+

etc.. for both + and -...

i have no idea where to start from

to those who think this is a homework problem: it was a problem we had in class today, i spent along time figuring a correct answer and I just found it by trial and error and it took a long time. teacher said there was 12 different answers and im just wondering as to what they are
