  • Solve problems involving standard form
​
End of term test
Expressions, Equations and Formulae
  • Solve linear equations
  • Change the subject of a formula
  • Manipulate formulae or equations to change the subject
Note: Expressions are Simplified, Equations are solved, Quadratic Expressions are Factorised, Quadratic Equations are Solved. Occasionally, Formulae may be rearranged, or an Equation may be rearranged to make a letter the subject
