P4.7.3 - Vector addition and scalar multiplication

Perform vector addition and scalar multiplication and interpret both operations geometrically.

Use vector addition and scalar multiplication to connect the rule to the data and decision in the question.

This matters because vector addition and scalar multiplication determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply vector addition and scalar multiplication to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Vector addition and scalar multiplication is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
