 This time, I'm going to convert these four numbers into the two's complement format. My first number is 53. So I will begin by converting this number into binary. And this time I have 32 plus 16 gives me 48 plus 5 gives me 53. So there is 53 in binary. Next, I'm going to write this number out using 16 bits. Since 53 is a positive number, I'm done. That's positive 53 in two's complement. My next number is negative 47. So 47 is 32, but it's one less than 48. So I will really have 32 plus 15. And this is a negative number. Again, I'll start by writing my number as a positive number. So there is positive 47, but I want negative 47. So I'm going to apply the two's complement operation to this. I will flip all of the bits, and I will add one to this. I would normally have a zero there. Zero plus one will give me a one. So there is the two's complement representation of negative 47. My third example is 39. 39 is 32 plus 7. So there's 39 in binary. And I'm just going to write this number with 16 bits again. And since 39 is a positive number, I'm done. That's positive 39 in two's complement. My last number is negative 41. In this case I have a negative number. It's 32 plus 9. There's negative 41 in binary. I'll start by writing down my magnitude with 16 bits. And now I'm going to apply the two's complement operation to this. Again, this is a negative number. So I want to convert this from positive to negative. So I will start by flipping all of the bits in my positive representation. And again, I would normally have a zero here. But the second part of my two's complement operation is to add one. So zero plus one would give me one. And there is negative 41 in the two's complement format.
