Show answers and working
  1. 1. -6

    Subtracting 8 is the same as adding -8. 2 + (-8) = -6

  2. 2. -14

    Subtracting 9 is the same as adding -9. -5 + (-9) = -14

  3. 3. 1

    Start at 0 on a number line. Move 1 right. You land on 1.

  4. 4. 2

    Subtracting 0 is the same as adding 0. 2 + 0 = 2

  5. 5. 220

    Multiply the sizes: 11 × 20 = 220. Same signs give positive, different signs give negative. Answer: 220

  6. 6. -12

    Start at 4 on a number line. Move 16 left. You land on -12.

  7. 7. 12

    Multiply the sizes: 2 × 6 = 12. Same signs give positive, different signs give negative. Answer: 12

  8. 8. -26

    Subtracting 19 is the same as adding -19. -7 + (-19) = -26

  9. 9. 31

    Subtracting (-6) is the same as adding 6. 25 + 6 = 31

  10. 10. 247

    Multiply the sizes: 13 × 19 = 247. Same signs give positive, different signs give negative. Answer: 247

  11. 11. -6

    Start at -26 on a number line. Move 20 right. You land on -6.

  12. 12. -17

    Subtracting (-8) is the same as adding 8. -25 + 8 = -17

Common mistakes

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

  • Thinks −8 is bigger than −3.

    Correction: Further left on the number line means smaller.

  • Treats − (−4) as −4.

    Correction: Two minus signs together become a plus.

Teacher tips

  • · Use a vertical number line like a thermometer.

Parent tips

  • · Compare winter temperatures from the weather forecast.

Real-life applications

  • · Temperatures below zero, bank balances, floors below ground.
