    Solving +/- 1

    How do I solve this when I see it presented in this format? What steps do I take to solve it?

    I know it has to do with the number line and can solve it if it was written like this: -1 - (-1) or 1 + (-1) and such. It's just the way it's written that has me confused. Thanks for the help!

    What is this? Give me an actual example where you saw it. There is nothing to solve if you just have +/- 1.

    If you had for instance x = sqrt(2) +/- 1. it means there are two solutions. x = sqrt(2) + 1 or x = sqrt(2) - 1
