tõeväärtusteks

Tõeväärtusteks is an Estonian term that translates to "truth values" in English. In logic and mathematics, truth values are the values assigned to propositions or statements to indicate whether they are true or false. The most common truth values are "true" and "false." These values are fundamental to the study of logic, serving as the basis for evaluating the validity of arguments and the consistency of statements.

In classical logic, every declarative statement is considered to have exactly one of two truth values: true or false. This principle is known as the law of excluded middle, which states that a proposition must either be true or false, with no intermediate possibility. This binary system is essential for constructing logical systems and performing logical operations such as conjunction (AND), disjunction (OR), and negation (NOT).

Beyond classical logic, other logical systems exist that allow for more than two truth values. These include multi-valued logics, which may incorporate values like "unknown," "possible," or even a range of values representing degrees of truth. However, the concept of truth values remains central to understanding how statements can be evaluated for their veracity within any given logical framework. The term tõeväärtusteks specifically refers to this core concept in the Estonian language.
