  • 1. MATH : ]
  • 2. Content
    • Why I like this subject?
    • Simultaneous Equations
    • Factorisation
    • Fractions
    • L.C.M & H.C.F
  • 3. Why do I like math?
    • It is very challenging
    • It enables us to think more.
    • It also helps us to use in our daily lives
    • Such as : counting our own money, paying bills
    • It also links to another subject which is Science.
  • 4. Simultaneous Equations
    • It is a set of equations containing multiple variables.
    • Examples:
    • 2 x + y = 3 and 4 x + 2 y = 6
    • 2 x + y = 3 and 6 x + 3 y = 7
  • 5. Solving Methods
    • It can be solved using different methods which is graphical, substitution or elimination method.
  • 6. Factorisation
    • To break down into simpler parts
    • So that is easier to solve.
    • Examples:
    • 24 x ² - 144 x + 216
    • 24[ x 2 - 6 x + 9]
    • 24[( x - 3)²]
  • 7. Fractions
    • A fraction is a whole number divided by another whole number.
    • Examples: ½ , ¾ , ¼
    • The top part is : numerator
    • The bottom part is : denominator
  • 8. L.C.M & H.C.F
    • L.C.M = Least Common Multiple
    • H.C.F = Highest Common Factor
    • Examples:
    • L.C.M and H.C.F of 6 and 12.
    • Solution:
    • 24 = 2 × 3 , 12 = 2² × 3
    • L.C.M = 2 × 3 H.C.F = 2² × 3
    • = 6 = 12
