Question
notation check: multiply the vector (22, 24) by 4. Show your working one step at a time.
Answer
The final answer is (88, 96). A vector calculation works component by component. Multiply each vector component by 4. 4 times 22 gives 88. 4 times 24 gives 96. (88, 96)
Explanation
exam warm-up keeps the canonical answer (88, 96) 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] Apply addition and subtraction of vectors and multiplication of vectors by a scalar..
Show the method first, then give the final answer in the required form. Apply this directly to Vector operations and proofs.
