Boolean Precedence Visualizer Enter a Boolean expression using T (true), F (false), ! (NOT), && (AND), || (OR), and () . Click 'Evaluate' to see the order of operations. Evaluate Evaluation steps will appear here. Operator precedence in Boolean algebra Operator precedence (also called operator order) tells you which Boolean operation is evaluated first when an expression contains several operators and no parentheses. Using precedence correctly avoids ambiguity and helps you evaluate or simplify expressions step by step. Common precedence order (highest → lowest) Priority Operator(s) Typical symbol(s) Description 1 (highest) Parentheses / Grouping ( ... ) Force evaluation of the grouped subexpression first 2 NOT (negation) ¬, !, ~ ...
