 This time we'll try multiplying 100 by 1000. Again, we expect we should get 100,000 out, but the work will look different in binary. So, I'll start by putting the larger of the two numbers on top, just the 1000, and I'll just copy that down from the table, and then 100 as well. So, zero times anything is zero. Zero times anything is zero. One times anything is the anything. So, I'll copy down the anything. And then I've got zero times anything is zero. Zero times anything is zero. One times anything is the anything. And one times anything is the anything. So, and now I just need to add up these three binary numbers. So, I've got a whole lot of zeros over here. Nothing else to do. Now I've got one plus zero is one. Zero, one, ten. So, one plus one is ten plus one is eleven. One, ten, eleven. One, ten, eleven, one hundred. So, now I've got two different options. I need to write down a zero. Now, I can either carry a ten, or I can look at this as carrying a one to this position. Either of these will do the same thing. We just might have to do some extra carrying later. So, if I put this here, you'll notice I'd have ten plus one plus one is also one hundred. Or I could put it here, in which case I'd have one plus one is one, and I'd have the one plus one is ten. So, that would, again, carry over to that, to this position again. So, if I do this, ten plus one plus one is one hundred. So, I'll write down a zero, carry a ten. Ten plus one plus one is one hundred. Zero, carry a ten. Ten plus one plus one is one hundred. Zero, carry a ten. Ten plus one is eleven. So, one, carry a one. And then I've got that. If I'd done this by carrying one hundred, say I'd got one plus one plus one plus one is one hundred. So, I'd write down the zero. I would carry a one to this position. And I'd have one plus one is zero. I'd carry a one. Now, I've got one plus one plus one plus one is a hundred, again. Put down zero, carry a one hundred. Now, I've got one plus one is zero. Carry a one. One plus one plus one is eleven. So, I'd write down a one. Carry another one. And I'd get the same number out, just depending on how you want to do the carrying there. And then again, I can compare this to my one hundred thousand. I've got one, one thousand. Zero, one, one, zero. Ten, ten, and zero. So, I get the same number out. Again, I get the number I expect.
