    Hi, electronic circuits are more or less black magic to me. I somehow managed to do the previous tasks I had to do but unfortunately the one I have now is somewhat beyond me:(

    I have to create parrarel adder capable of adding two 4 bit numbers using 4 bit adder. The outcome should be read out from the registry in parrarel method (Im not sure if i translated this correctly)

    Equipment-
    4 invert gates
    2 NAND (2 entrances)
    8 EX-OR (2 entrances)
    74164 x2
    74165 x 2
    7483 (one bit adder) x1
    74175 x1
    74198 x 1
    7475 x1
    7495 x1


    I will be insanely greatful for help

    What have you done so far?

    If you look at the datasheet of 7483, it is a 4-bit full adder by itself. ;)

    I think he may be confusing parallel with serial. Based on how he described the output as being "read out".
