Positive And Negative
In mathematics, the sign of a real number is its property of being either positive, negative number, negative, or 0. Depending on local conventions, zero may be considered as having its own unique sign, having no sign, or having both positive and negative sign. In some contexts, it makes sense to distinguish between signed zero, a positive and a negative zero. In mathematics and physics, the phrase "change of sign" is associated with exchanging an object for its additive inverse (multiplication with −1, negation), an operation which is not restricted to real numbers. It applies among other objects to vectors, matrices, and complex numbers, which are not prescribed to be only either positive, negative, or zero. The word "sign" is also often used to indicate binary aspects of mathematical or scientific objects, such as odd and even (Parity of a permutation, sign of a permutation), sense of Orientation (vector space), orientation or rotation (clockwise, cw/ccw), one sided limits, ...
