First order logic operator precedence
WebIn 1st order logic equality statements use the equal /2 predicate, or infix = /2 and != /2 predicates. Example Axioms even (sum (two_squared,b)) two_squared = four ∀X (zero (X) => difference (four,X) = sum (four,X)) zero (b) Conjecture even (difference (two_squared,b))
