Exam-style question
Try this first
Add the two-dimensional vectors (1, 2) and (3, 4).
- A.(4, 6)
- B.Not (4, 6)
- C.(4, 6) only sometimes
- D.(4, 6) with no working
Model answer
What a good answer should say
- The correct answer is (4, 6).
This answer is tied to the objective: J1 Use vectors in two dimensions and in three dimensions..
Explanation
Why this works
Use the explanation to connect the worked answer back to J1 Use vectors in two dimensions and in three dimensions..
Use the worked steps as the check: the question intent fixes the answer as (4, 6), and the final-answer line confirms (4, 6).
Maths method check
