Scopul Lucrării: Lucrarea prezintă instrucțiunile pentru transferuri de date,instrucțiunile în aritmetica binară şi în aritmetica BCD. Sarcina Lucrării: Conform variantei elaboraţi 2 variante de program : a)cu introducerea datelor de la tastatură şi afişarea rezultatelor pe ecran. b)cu generarea datelor de intrare, utilizănd procedurile Random32, RandomRange. Varianta 7 𝑌/2 + 𝑋, 𝑍={ 2𝑌 + 32𝑋

𝑑𝑎𝑐ă 𝑌/2 > 0 , 𝑑𝑎𝑐ă 𝑌/2 ≤ 0

Concluzie In lucrarea de laborator nr.3 am realizat un program ce rezolva o operatie.Au fost obtinute noi abilitati in utilizarea instructiunilor in aritmetica binara:adunare,scadere,inmultire,impartire si utilizarea salturilor conditionate si neconditionate.De asemenea am utilizat procedurile Random32 si RandomRange.
