Key Topics to Revise

1

Need for Negative Numbers

  • When a larger number is subtracted from a smaller number, the result is negative.
  • Negative numbers are used to represent values below zero.
  • Examples: temperature below 0°C, loss in business, depth below sea level.
2

Integers and Number Line

  • Integers include positive numbers, negative numbers, and zero.
  • Zero is neither positive nor negative.
  • On a number line, positive integers are to the right of zero, negative to the left.
3

Ordering and Comparing Integers

  • On a number line, numbers increase from left to right.
  • Every positive integer is greater than every negative integer.
  • Zero is greater than every negative integer but less than every positive integer.
4

Operations on Integers Using Number Line

  • Addition: move right for positive, left for negative.
  • Subtraction: move in the opposite direction of the number being subtracted.
  • To subtract a negative number, add its positive counterpart: e.g., 4 – (–3) = 4 + 3 = 7.
