Why does an unmatched label give NaN?
Short answer. Pandas matches by label, so that value has nothing to pair with.
How do you avoid NaN when adding?
Use the add method with fill_value=0.
Remember
| Maths works label by label |
| Unmatched labels give NaN |
You added two Series and got N a N. Why? Pandas adds by label, not position. Label Om and label Anu never match. So both answers are N a N, meaning missing. Two rules. Maths works label by label. Unmatched labels give N a N.
