MathNotation

Set theory and logic symbols

∩	X ∩ Y	the intersection of the sets X and Y
∪	X ∪ Y	the union of the sets X and Y
\	X \ Y	the difference of set X minus set Y
⊂	X ⊂ Y	X is a proper subset of Y

Boolean operations

¬	¬ a	not a	negation
∧	a ∧ b	a and b	conjunction
∨	a ∨ b	a or b	disjunction
		either a or b	alternation
⇒	a ⇒ b	if a then b	implication
⇔	a ⇔ b	a if and only if b	equivalence
