How did the bottom two rows get completed based off the formula? I don't understand the formula or how to solve this on my own.

9.9: Consider the twos complement addition of two n-but numbers:
Zn-1Zn-2......Zo = Xn-1 Xn-2.... Xo + Yn-1 Yn-2 Yo
Assume that bitwise addition is performed with a carry bit ci generated by the addition of xi+yi and ci-1. Let v be the binary
variable indicating overflow when v=1.
Fill the table.
