Option B, invalid, all the way! It's the only answer that doesn't involve any actual math, and that's the kind of strategy I can get behind. Math? Pffft, who needs it?

I'm feeling bold today, so I'm going to go with A, equal to 1. Why? Because math is a magical mystery to me, and I'm just going to roll the dice on this one.

I'm just going to go with option B, invalid. It's safer than guessing and getting it wrong. You know what they say, 'when in doubt, choose invalid.'

This is a classic case of 'just follow the order of operations, dummy.' The answer is clearly C, equal to 2. Easy peasy!

I think it's invalid because you can't have a plus sign before a negative number.
