Answer 3

Let's simplify the given expression step by step:

1. Start with the expression: (+1 / -1 - -1 / +1) - 1/

2. Evaluate the divisions first: (+1 / -1) = -1 (-1 / +1) = -1

So now the expression becomes: (-1 - -1) - 1/

3. Simplify the subtractions: (-1 - -1) = (-1 + 1) = 0

Now the expression becomes: 0 - 1/

4. Finally, we have a division left. Since there's no denominator after the 1, the expression is not well-defined. Division by zero is undefined in mathematics.

Therefore, the expression you provided is undefined.
