definition :
  principe  additif c'est deux ensembles disjoint
  s'ils n'ont aucun element en commun

  principe multiplicatif produit cartesien
  couple, triplets, p-uplets a1EE1...apEEp
  demonstration : A=(1;2;3) B=(0;1) Card(B)*Card(A)=2*3=6
  
  p-uplets ensemble n: n entier et E ensemble non vide
  E*E*E=E**p
  on a donc Card(E)**p
  E(A;B;C) P=5 =3**5
  
  Arangement de p elements de E est un p-uplets
  d'elements distincts de E qui ne se repete pas
  
  partie d'un ensemble: E un ensemble F
  tel que tous les elements de F appartiens 
  aussi a E. On dit que F est un sous ensemble de E
  
  combinaison : une combinaison de p elements de E
  est une partie ayant p element
