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))
