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: J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
Explanation
Why this works
Use the explanation to connect the worked answer back to J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
The locked answer is (4, 6). Work through the given values, keep one operation per line, and check the final step reaches (4, 6).
Maths method check
