Nuprl Lemma : multiply_distrib_int_mod
∀[n:ℤ]. ∀[a,x,y:ℤ_n]. ((a * (x + y)) = ((a * x) + (a * y)) ∈ ℤ_n)
Proof
Definitions occuring in Statement :
int_mod: ℤ_n,
uall: ∀[x:A]. B[x],
multiply: n * m,
add: n + m,
int: ℤ,
equal: s = t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
int_mod: ℤ_n,
quotient: x,y:A//B[x; y],
and: P ∧ Q,
all: ∀x:A. B[x],
implies: P ⇒ Q,
prop: ℙ,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
uimplies: b supposing a,
iff: P ⇐⇒ Q,
rev_implies: P ⇐ Q
