This is an example of terminal digit filing. When filing by your terminal digit, you're actually using the very last digit that's in your number series. And then you just place them in numeric order. So in this example, 1 is first, 34 is second, 35 is third, 60 is fourth, 71 is fifth.
and 82 is last. In this example, we have two terminal digits that are the same. Therefore, we continue to move to the left and check out the middle digit.
So, for this example, this is number 1, and this one will be number 2. So, our next number in line is going to be our 71s. is smaller than 33. So 32 will be 3 and 33 will be 4. And then we have 82. 10 is smaller than 11. So this will be 5 and the last one will be 6.
