How to solve
To draw u + v, place the tail of v at the head of u. The sum runs from the original tail to the final head.
Steps
- Add corresponding components.
- Locate the final head in the diagram.
- Read the requested coordinate of u + v.
Example
u = ⟨2, 1⟩ and v = ⟨−1, 3⟩.
- u + v = ⟨2 − 1, 1 + 3⟩.
- u + v = ⟨1, 4⟩.
Answer: 1 or 4 depending on the requested component
