Positive and Negative Numbers

Topic promise: By the end of this topic, you’d know how mathematical operations impact positive and negative numbers

Topic duration: 7 minutes

All numbers can be divided into 3 categories:

  • Positive
  • Negative
  • 0 (0 is neither positive, nor negative)

Positive number: Any number to the right of 0 on number line

Negative number: Any number to the left of 0 on number line

 

x is positive is equivalent to saying x > 0

x is negative is equivalent to saying x < 0

x is neither positive, nor negative is equivalent to saying x = 0

 

pos x pos = pos

pos x neg = neg

neg x neg = pos

(same for division)
