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.

While the rules say you can replace a space with + or - it doesn't say you can eliminate a space.

However, once one does that, one can go up to 123,456,789 (commas inserted for clarity), with various gaps of course.
