There's a problem on my math homework that I really don't get. I couldn't find it anywhere else on the internet, so I came here. I have to use the numbers
1, 2 ,3, 4, 5, 6, 7, 8, and 9 and I can multiply, divide, add, and subtract, but I can't use parenthesis
to make an expression that will equal 100. I played around for a while and didn't get anything. Plus, I can't use the expression
123-4-5-6-7+8-9=100, because that's the example they gave in the book.
So, could someone help me out here? Thanks. :smile:

23*5 - 9 - 8 - 7 - 1 + 6 + 4
That's also one.
 
Thanks! :smile:
 
Whoops! I forgot to say that the numbers had to be in consecutive order. Crap. Well, thanks anyway.
 
1+23*4+5-6+7-8+9=100:smile:
1+2+3+4+5+6+7+8*9=100:smile:
