The first problem: Given the expression:
+1+2+3+4+5+6+7+8+9+10

Either find a way to change some of the plus signs to minus signs in order to make the entire expression equal zero, or prove that there is no way to do it.

Since this one is easy, I'll do it quick.

1+2+3+4+5+6+7+8+9+10 = 55

55 is odd. In order for your numbers to cancel out to zero, you'll need to split 55 so the the positive value equals the negative value. That can only happen if the total is even.

If those kind of questions were on the SAT, only 1 out of a 1000 people would go to college ;)

Since this thread was posted as one of the top 20 posts I personally don't considder this as dead. So what's your f*cking problem. Since it was posted in GH I didn't read weather an answer to the Q was given or not.
