**Lesson Steps**:

First, you add 8+7, this equals 15. Add the 1 to the 9 and then add 10+6, and this equals 16. Add the 1 to the 1 and then add 2+5, which equals 7. Then you add 9+3, which equals 12. Add the 1 to 6 to get 7. Since there is nothing to add the 0 and the 5 to, you simply bring them down. And now, you have the answer 5,072,765
