Nuprl Lemma : rmul-ac
∀[a,b,c:ℝ]. ((a * b * c) = (b * a * c))
Proof
Definitions occuring in Statement :
req: x = y,
rmul: a * b,
real: ℝ,
uall: ∀[x:A]. B[x]
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
uiff: uiff(P;Q),
and: P ∧ Q,
rev_uimplies: rev_uimplies(P;Q),
implies: P ⇒ Q
Latex:
\mforall{}[a,b,c:\mBbbR{}]. ((a * b * c) = (b * a * c))
