10.1- Introduction
Solve simple linear equations in one unknown
• solve fractional equations with numerical and linear algebraic
denominators
• solve simultaneous linear equations in two unknowns
• solve quadratic equations by factorisation, completing the square
or by use of the formula
• solve simple linear inequalities
10.2- Solving Linear Equations
Solve linear equations in one unknown algebraically (including those with the unknown on both sides of the equation); find approximate solutions using a graph
10.3- Quadratic Equations
Solve quadratic equations algebraically by factorising; find approximate solutions using a graph
10.4- Simultaneous Equations
Solve two simultaneous equations in two variables (linear/linear algebraically; find approximate solutions using a graph
10.5- Approximate Equations
An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding. A calculation can be approximated by rounding the values within it before performing the operations.
10.6- Inequalities
Solve linear inequalities in one variable; represent the solution set on a number line
