The CPU could do the four fundamental functions of arithmetic -- so addition, multiplication, subtraction, division -- which already is a bit of a feat in metal, but it could also do something that a computer does and a calculator doesn't: this machine could look at its own internal memory and make a decision.
Unitatea CPU putea face cele patru funcţii fundamentale ale artimeticii: adunare, înmulţire, scădere, împărţire -- ceea ce deja e o performanţă în metal, dar mai putea face ceva ce face un computer dar nu un calculator: această maşinărie putea lua o decizie pe baza memoriei interne.
