OMG. I can do multiplication when its 110101 x 0110 = 1110111110
this would give me an answer of -66 when converted to dec.
however, i cant seem to get the answer of -66 when 010110 x 1101 = 1110111110
am i correct to say that 010110 = 22 and 1101 = -3, hence 22 x -3 = -66
but the answer i got was 0100011110 which means it is a positive number which doesnt make any sense.
