Notation N = { 1 , 2 , 3 , 4 ,... } is the set of natural numbers. Z = { 0 , ± 1 , ± 2 , ± 3 ,... } is the set of integers. Q = { p q | p,q Z and q 6 = 0 } is the set of rational numbers. I = { x R | x / Q } is the set of all irrational numbers. These are numbers which can be represented by infinite decimals. R = Q I is the set of all real numbers. • ∅ is the empty set • ∃ is the existential quantifier. It is the mathematical symbol for ”there exists”. • ∀ is the unviersal quantifier. It is the mathematical symbol for ”for all”. • ∈ is the mathematical symbol for ”is an element of”. • ⊂ is the mathematical sybmol for ”is a proper subset of”. • ⊆ is the mathematical symbol for ”is a subset of”. is the mathematical symbol for ”therefore”. is the mathematical symbol for ”because”. • ∼ can be used as the matematical symbol for negation.
