Question
notation check: add the vectors (22, 24) and (22, -21). Show your working one step at a time.
Answer
The final answer is (44, 3). A vector calculation works component by component. Add the x-components. The x-component is 44. The y-component is 3. (44, 3)
Explanation
exam warm-up keeps the canonical answer (44, 3) fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Vector operations and proofs common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Use diagrammatic and column vector representations to construct geometric arguments and proofs..
Show the method first, then give the final answer in the required form. Apply this directly to Vector operations and proofs.
