Proof
Definitions occuring in Statement :
rv-mul: a*x,
rv-add: x + y,

radd: a + b,
int-to-real: r(n),
real: ℝ,
ss-eq: x ≡ y,
ss-point: Point,
uall: ∀[x:A]. B[x],
natural_number: $n
Definitions unfolded in proof :

member: t ∈ T,
ss-eq: x ≡ y,
not: ¬A,
implies: P ⇒ Q,
false: False,
subtype_rel: A ⊆r B,
prop: ℙ,
all: ∀x:A. B[x],
uimplies: b supposing a,
uiff: uiff(P;Q),
and: P ∧ Q,
rev_uimplies: rev_uimplies(P;Q)
