Nuprl Lemma : coprime-mod

n:ℕ+. ∀x:ℤ.  (CoPrime(n,x) ⇐⇒ CoPrime(n,x mod n))


Proof




Definitions occuring in Statement :  coprime: CoPrime(a,b) modulus: mod n nat_plus: + all: x:A. B[x] iff: ⇐⇒ Q int:
Definitions unfolded in proof :  all: x:A. B[x] member: t ∈ T iff: ⇐⇒ Q and: P ∧ Q implies:  Q prop: uall: [x:A]. B[x] nat_plus: + rev_implies:  Q subtype_rel: A ⊆B
