Logic syntax defines the rules for constructing valid expressions in formal logical systems. Below is a structured overview of key elements in common logics, such as propositional and first-order logic.<\/p>\n

## Propositional Logic
\n– Atomic Propositions: Basic statements represented by letters (e.g., p, q, r). These are the simplest units.
\n– Connectives:
\n – Negation: \u00acp (not p)
\n – Conjunction: p \u2227 q (p and q)
\n – Disjunction: p \u2228 q (p or q)
\n – Implication: p \u2192 q (if p then q)
\n – Biconditional: p \u2194 q (p if and only if q)
\n– Well-Formed Formulas: Expressions formed by combining atomic propositions with connectives, following operator precedence (e.g., \u00acp \u2227 q is valid).<\/p>\n

## First-Order Logic
\n– Terms:
\n – Constants: Fixed values (e.g., a, b).
\n – Variables: Placeholders (e.g., x, y).
\n – Functions: Operations on terms (e.g., f(x) for a function f applied to x).
\n– Predicates: Statements about terms (e.g., P(x) means “x has property P”).
\n– Quantifiers:
\n – Universal: \u2200x (for all x)
\n – Existential: \u2203x (there exists x)
\n– Well-Formed Formulas: Built from predicates, terms, and quantifiers, combined with connectives (e.g., \u2200x (P(x) \u2192 Q(x))).<\/p>\n

## General Rules
\n– Parentheses: Used for grouping (e.g., (p \u2227 q) \u2228 r to specify order).
\n– Syntax Validity: Formulas must adhere to formation rules to avoid ambiguity; for example, quantifiers must bind variables properly.<\/p>\n

This overview covers foundational syntax; extensions exist in modal, temporal, or programming logics like Prolog.<\/p>\n
