 For this example, I'm going to start with some small numbers that appear in our number line, and we're just going to multiply them in binary. So if I start with something really simple, like five times three. I should get 15 out, and you can see what the binary value is for 15 there. But we'll work through this in binary. So one times one gives me one. One times zero gives me zero. One times one gives me one. Again, basically anytime I see a one in one down here, I'm just going to copy down whatever the top number is. So, got a one, so one, zero, one. And I just have to make sure it's lined up with this bit. Now I go through, I do the addition. One plus zero is one. Zero plus one is one. One plus zero is one. And zero plus one is one. And I can look over, I can see that yes, that is indeed 15 in binary. If I try something else like four times two, I should expect to get eight out. So I have zero times anything is zero. So I'll just have a zero in that place. And then one times anything is the anything. So I'll write down the anything. And I don't even have any addition to do this time. I can just look over and see that that is eight in binary. If I do something like three times three, one times anything is the anything. And then one times anything is the anything. Now I'll add these up. One plus one is ten. So I get 1001, which is nine in binary. If I do five times two, and zero times anything is zero. One times anything is the anything. So, and I get ten in binary.
