Ordinea efectuării operațiilor (I)
* Înmulțirea este o operație de ordinul al doilea;
* Adunarea este o operație de ordinul întâi, deoarece prin adunarea repetată de termeni egali se rezolvă înmulțirea;
* Scăderea, ca și adunarea, este o operație de ordinul întâi;
* Dacă un exercițiu conține una sau mai multe operații de ordinul întâi și de ordinul al doilea, rezolvăm mai întâi operațiile de ordinul al doilea, apoi pe cele de ordinul întâi.
