Before you start

Have a wander along the line — nothing here is right or wrong. See how far each number sits from zero, and which side of it.

-6-5-4-3-2-10123456

Zero is not a wall. Going from -3 up to 2 walks straight through it and out the other side.

  1. 1.-10 - (-4) = ?

  2. 2.5 - 12 = ?

  3. 3.Put these integers in order, smallest first.

    • 3
    • -1
    • -12
    • 0
    • -5
    • 9

  4. 4.-4 + 11 = ?

  5. 5.-7 + 3 = ?

  6. 6.Which number is greater: -3 or -9?

    • a) You cannot compare negative numbers
    • b) They are equal
    • c) -3
    • d) -9

  7. 7.-8 - 6 = ?

  8. 8.Work out each one, then sort it by whether the answer is negative or positive.
