Nuprl Lemma : rv-add-minus

[rv:RealVectorSpace]. ∀[x:Point].  -x x ≡ 0


Proof




Definitions occuring in Statement :  rv-minus: -x rv-add: y rv-0: 0 real-vector-space: RealVectorSpace ss-eq: x ≡ y ss-point: Point uall: [x:A]. B[x]
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T rv-minus: -x ss-eq: x ≡ y not: ¬A implies:  Q false: False subtype_rel: A ⊆B prop: all: x:A. B[x] uimplies: supposing a uiff: uiff(P;Q) and: P ∧ Q rev_uimplies: rev_uimplies(P;Q)
