  - - - Rational numbers come in 3 different forms:
        
        Integers: -5 (= -5/1), -12 (= -12/1), 4 (= 4/1
        
        Fractions p/q, where p and q are (non zero) integers: 1/4, -1/2, 7/4
        
        Terminating or recurring decimals: 0.125 (= 1/8), 0.333333333... (= 1/3), 0.143143143143... (= 143/999)
    - - Square roots of positive integers are either integers or irrational. e.g. square root of 2 or 3 are irrational, but square root of 4 = 2 isn't.
      - Surds are numbers or expressions containing irrational roots.
      - Pi is also irrational
  - - - BODMAS tells you the order in which these operations should be done.
    - - Then work out any others - like squaring
        
        You then divide if you need to
        
        Next multiply
