Any positive number x has two square roots: one positive and one negative. For example, +3 and -3 are both square roots of 9. Using a brilliant leap of imagination, mathematicians decided to call the first of these the positive root!
We call this Conventional Current Flow, where imaginary positively charged particles are repelled away from a positive charge and attracted towards a negative charge.The reality is that electrons are actually flowing through the conductor. Electrons are negatively charged particles and flow from negative to positive. It's just easier to think of a positive current flowing than a negative current.
Positive and negative reinforcement both call attention to a situation. For many, negative attention is more desirable than no attention. Negative reinforcement is generally quicker than positive, yet the positive is so very important for development including self esteem.

You can consider any direction as positive, and the opposite direction as negative. However, in this case it is customary to call a gain "positive", and a loss "negative".
I would call that positive.
A balance of negative and positive charges is called neutrality. This occurs when the total negative charge is equal to the total positive charge, resulting in a system that is electrically neutral.
You can assign positive numbers to east and negative to west - or you can do it the other way round. Which direction you call positive is really quite arbitrary. In Google Maps for example, east appears as positive.
