0 1 2 3 4 5 6 7 8 9

You have to put in + and - signs in the blanks, so that in the end it will all equal 1.

Also, if possible, try to make expressions resulting in 0 and -1.

The allowing of the deletion of a space, rather than only replacement by + or - makes this the equivalent of "Plus and Minus".
