expresie

Expresie is a Romanian term meaning expression, used across mathematics, logic, computer science, and everyday speech. In mathematics, an expresie is a combination of numbers, variables and operators that can be evaluated or simplified, but it does not include an equals sign. In logic and programming, expresie denotes a construct that evaluates to a value, potentially used in conditions or assignments. In ordinary language, expresie can refer to a manifestation of thought or feeling, such as an facial expresie or artistic expresie.

Types and examples: algebraic expressions like 3x+2, numeric expressions like 7, and more complex ones such as sqrt(4+x) or sin(y). Boolean expressions use logical operators such as and, or and not, producing true or false. In programming, expressions may combine variables, literals, and operators, and may have side effects depending on the language. Some languages treat assignment as an expression, while others treat it as a separate statement.

Education and terminology: Expresie is a foundational concept in Romanian mathematics and computer science curricula, paralleling the English term expression. The concept distinguishes expressions from equations and statements. In linguistics and art, expresie emphasizes conveyance of mood or meaning, including facial expressions and expressive style in writing or performance.

Origin: Expresie derives from Latin expressio, via French and other languages, and is now standard in Romanian to cover both the mathematical and everyday senses of expression.
