32:00 you did STO 201, so you just copied the value of ACC to address 201 and ACC remains unchanged?

[johnyangsana]

24:11

ADD 200, where location on 200 contain Address <18>. And Address <18> contain 200. ACC should 400 + 200 = 600. Not 400 + 18.

[bilaltaj]

When we havent loaded anything in the accumulator and just started our program do we assume that the accumulator has "0" in it?

[bilaltaj]

When the instruction says load something to the accumulator for e.g LDD #21, what happens to the value already stored in the accumulator? does it get replaced or added?
