 Alright, let's take a look at another example of addition. So we'll add 3, 5, 3, 3 base 8 plus 2, 7, 6 base 8. And I'll set up a place value chart. And because I'm working in base 8, each unit is going to be 8 of the next smaller unit. So I'll set up my place value chart with a bunch of columns. If I need more, I'll just add additional columns at the end, but I'll set them up this way. And my rightmost column is my ones. Eight of these will form the next, so eight ones, I'll call them eight. My next column is going to be eight, eights. Well, I don't really care what these are. Again, we don't actually need to know what these units are. We don't need to really know how big they are. All we need to know is that there's a trade rate, eight of anything, is one in the next place over. So I don't really need to know the names, and I'll just omit them. And I'll set down my add ends. And again, I'll add, staying within each place. And again, for convenience, I'll use my familiar symbols for the higher numbers, even though in base 8 these symbols don't really exist. And it doesn't really matter the order that I add in. So I'll add from left to right, that's 3, 7, 10, and 9. And then I'm going to bundle sets of eight. Now it didn't matter which order I added, but it's convenient if I bundle in trade from right to left. And again, the reason for that is sometimes we'll get extra things in a column from the next place over. So if we go from left to right, we may have to retrace some of our steps. So starting with the rightmost column, 9, again I'm looking for sets of eight. So 9 is an 8 and 1, so I'll bundle, there's my 9, and trade 8 gives me one of the next place over. And I'll combine these two. And I'll look for that bundle, 11 is 8 and 3, there's my bundle, and I'll trade. And I'll add, combine, and that's an 8. I'll bundle, well 8 is itself a bundle, and there's going to be nothing left over, so I'll trade and combine, and I can read off my number for 0, 3, 1, base 8.
