\(\Large 1 \ \square \ 2 \ \square \ 3 \ \square \ 4 \ \square \ 5 \ \square \ 6 \ \square \ 7\)
If we only used plus signs and minus signs in place of the boxes above, how many distinct values can we obtain?
Maybe it is \(2^6\) but you probably have to minus the repeats.
Yeah, I think itś 2^6.
There are 2 possibilities for the first
There are 2 for the second
There are 2 for the third. This goes on...
