    4b = (8, 24). Add components: (3 + 8, -6 + 24).

  8. 8. (18, -24)

    4b = (20, -20). Add components: (-2 + 20, -4 + -20).

  9. 9. 3.61

    |v| = √(x² + y²) = √(4 + 9). = 3.61.

  10. 10. 6.4

    |v| = √(x² + y²) = √(25 + 16). = 6.4.

  11. 11. 7.81

    |v| = √(x² + y²) = √(36 + 25). = 7.81.

  12. 12. 2

    |v| = √(x² + y²) = √(4 + 0). = 2.

Common mistakes

What learners typically get wrong, and how to fix it.

  • Adds x of one vector to y of the other.

    Correction: Add x with x, y with y.

  • Forgets that a negative component means the opposite direction.

    Correction: Draw the vector to check.

Teacher tips

  • · Draw vectors on squared paper end to end.

Parent tips

  • · Give directions as '3 steps right, 2 steps up'.

Real-life applications

  • · Navigation, forces in physics, game movement.
