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: J3 Add vectors diagrammatically and perform the algebraic operations of vector addition and multiplication by scalars, and understand their geometrical interpretations..
Explanation
Why this works
Use the explanation to connect the worked answer back to J3 Add vectors diagrammatically and perform the algebraic operations of vector addition and multiplication by scalars, and understand their geometrical interpretations..
The distractors change the result or the form of the answer. The canonical solution reaches (4, 6), so (4, 6) is the only option consistent with the working.
Maths method check
