Zero itself is neither positive nor negative. The non-negative numbers are the real numbers that are not negative . The non-positive numbers are the real numbers that are not positive (they are negative, a number that is greater than 0
- Positive operator In mathematics, especially functional analysis, a hermitian element A of a C*-algebra is a positive element if its spectrum consists of positive real numbers. More strongly, an element x of a C*-algebra A is positive if and only if there is some b in A such that x = b*b. A positive element is self-adjoint and thus normal, in functional analysis, a bounded linear operator whose spectrum consists of positive real numbers
- Positive formula Typically, the motivation for these theories is topological: the sets are the classes which are closed under a certain topology. The closure conditions for the various constructions allowed in building positive formulas are readily motivated : the justification of the existential quantifier seems to require that the topology be compact, a logical formula not containing negation

- Plus sign The plus and minus signs are mathematical symbols used to represent the notions of positive and negative as well as the operations of addition and subtraction.

Philosophy and humanities
- Positive science One usage refers to analysis or theories which only attempt to describe how things are, as opposed to how they should be. In this sense, the opposite of positive is normative.

- Positive freedom Positive liberty refers to having the power and resources to act to fulfill one's own potential, as opposed to negative liberty, which refers to freedom from restraint. Inherent to positive liberty is the idea that liberty is the ability of citizens to participate in their government. As Isaiah Berlin noted, positive liberty is interested in, the opportunity and ability to act to fulfill one's own potential
- Negative and positive rights Some philosophers and political scientists make a distinction between negative and positive rights . According to this view, positive rights are those rights which permit or oblige action, whereas negative rights are those which permit or oblige inaction. These permissions or obligations may be of either a legal or moral character. Likewise, the, concerning the moral obligation of a person to do something for/to someone

- Positive economics Positive economics is the branch of economics that concerns the description and explanation of economic phenomena . It focuses on facts and cause-and-effect relationships and includes the development and testing of economics theories. Earlier terms were value-free economics and its German counterpart wertfrei economics. These terms were challenged, in economics, about predictions of behavior of economic actors, as opposed to the normative aspect
- Affirmative, in linguistics Linguistics is the scientific study of natural language. Linguistics encompasses a number of sub-fields.
