I was looking for you and I walked down 3 floors from your apartment and up 7 floors. I walked a whole 10 floors. |-3|+|7|. The sentence gives me 3+7=10.
But i was just in the candy palace. All you needed to do was walk 0+-4. Meaning, just walk down 4 floors.
I put my apartment on the 16th floor because I love this amazing, big kitchen
My plan for today is to go to the pool and then head straight to the arcade andplay some games. I will have to walk down 8 floors to the pool and then go 2 floors up to the arcade. I would then be at -8=10=18 . Meaning my final destination will be 18 floors above me at the arcade.
Hey why don't you come by my apartment. I only live 5 floors below you.
That sounds great! Let me just go make sure my time is not up for the parking garage. This means i will have to walk down 25 floors and then walk up 21 floors to you . So ill be going -25+21=-5. This means I'll be 5 floors under my apartment.
