For this problem, we need to find the product of 324 times 81. So let's start with our 1's values. We have 1 x 4, which is 4. Next, we're going to do 1 x 2, which is 2. And then 1 x 3, which is 3. Now we need to multiply 8 by 324, and since 8 is in the tens column, we need to add a 0 here in our next line in the 1s column. So now we're going to do 8 x 4, which is 32, so we gotta carry the 3 and place our 2 here. Now we have 8 x 2, which is 16, and we need to add the 3 from the previous step, so we get 19, we'll carry the 1 and place our 9 here. And next we do 8 x 3, which is 24, and we need to add the 1 from the previous step, so we get 25. Let me write that here. Now with our two partial products, we're going to add them together to get our final product. We have 4 + 0 is 4. 2 + 2 is 4. 3 + 9 is 12, so we got to carry the 1, place our 2 here. 5 + 1 is 6, and 2 + 0 is 2. So our final answer is 26,244.
