now

let u be set ; :: thesis: ( u in HT (P -Ideal ),T implies u in multiples (HT P,T) )
assume A2: u in HT (P -Ideal ),T ; :: thesis: u in multiples (HT P,T)
then reconsider u' = u as Element of Bags n ;
ex b' being bag of n st
( b' in HT P,T & b' divides u' ) by A1, A2;
hence u in multiples (HT P,T) ; :: thesis: verum

hence HT (P -Ideal ),T c= multiples (HT P,T) by TARSKI:def 3; :: thesis: verum
