 Let's continue our progress towards developing the standard algorithm, and so again the key concepts that we want to keep in mind are multiplication is a repeated addition, the properties of the whole number multiplication, and again the base trade rate. So let's take a harder product, 38 times 62, and so the product 38 times 62 is the same as the sum of, again, 38, 62, so we'll set down a place value chart, arithmetic is bookkeeping, so we'll keep track of the amounts that we have. So I want to find a whole bunch of 62s, so here I have 6 tens, 2 ones, 100s, 1000s, and maybe I'll need more places, but I'll add in a couple of places and add in more places as necessary. And I want 38, 62s, well 38, 62s, 38 is 30, and 8, so I'll start with 30, 62s, so well that's 36s in the tens place, that's 180, and again I should bundle and trade as I go along so that trade rate of 10 for 1, that 180, becomes 18 in the next place, I'll bundle and trade, and there's my 36s, and likewise I'm going to need 32s, and so that's going to be 32s here, so all together that's going to be 60, and again I'll do the bundle and trade. I also need 8, 62s, so I'm going to take 8, 6s, so that's going to get me 48, so there's my 8, 6s, 48, I'll bundle and trade, and I also need 8, 2s, that's 16, and bundle and trade, and so there's my 36s, 8, 30, 62s, there's my 8, 62s, all together I have 38, 62s, and again arithmetic is bookkeeping, so I'm just going to add everything together. Now I'm going to do this in two steps using what we had previously called totals below, just to make my life easier, and so I have 6 ones, I have, let's see, this is 1, 7, 15 tens, I have 8 and 4, I have 12, 100s and 1,000, and again I should bundle and trade just to make my life easier, so I will bundle and trade, and then I do one more total, and there's my final answer, 2, 300s, 5 tens, 6, and there's my product, 38 times 62.
