Electronic calculating circuit for all 4 calculation types

摘要

The calculator includes a flip-flop which is toggled to its off state by the output of the pulse circuit. The storage cells rows are disposed in the same direction as the shift registers. The main circuit of the calculator consists of a switchable tetrade circuit for addition and subtraction.A gate circuit system performs the number transfer operations using storage cells and the shift registers. A previous result can be used as a summand or minuend or multiplicand or dividend for further calculations.
