expressing

Expressing is the act of conveying meaning, intention, or feeling through language, gesture, art, or behavior. It encompasses linguistic expression (spoken or written), nonverbal cues, and creative forms. Expression is a core component of communication, social interaction, and culture, enabling individuals to share information, negotiate meaning, and respond to others.

In mathematics and logic, an expression is a combination of symbols that represents a value or quantity. Examples: 3x + 2, sin(π/4), or a boolean expression (a and not b). An expression can be simplified or evaluated, while an equation states equality between two expressions. Expressions contrast with statements that have a truth value.

In computer science, an expression is a construct that evaluates to a value. Programs use expressions in arithmetic, logic, and data access. They obey language-specific syntax and operator precedence, and may involve variables, literals, and function calls. Expressions can be constant, side-effecting, or lazy/evaluated as needed by the language.

In culture and society, expressing oneself is linked to personal identity, art, and freedom of expression. Visual arts, music, writing, and performance convey emotion and ideas. Legal and ethical norms govern expression, balancing individual rights with public safety and respect for others.
