OPPOSITE NUMBERS: My "Complete Idiot's Guide To Algebra" p.9, states: "The opposite of a number is indicated by a lone negative sign out in front of it. For example, the opposite of -3 would be written like this: -(-3). The value of a number's opposite is simply the number multiplied by -1. Therefore, the only difference between a number and it's opposite is its sign."
They offer 2 samples; one of which is a fraction I can not duplicate here. The other is the one that puzzles me: -(4) = -4 I see the signs as the same. Can you explain what I don't see?
Thank you. John :?:
