    • Algebraic expressions - AQA

      Letters can be used to stand for unknown values or values that can change. Formulas can be written and equations solved in a range of problems in science and engineering.

    • Algebraic formulae - AQA

      Formulae are used in everyday life, from working out areas and volumes of shapes to converting units of measurement. Knowing how to use and rearrange formulae are very useful skills.

    • Solving linear equations - AQA

      Forming, using and solving equations are skills needed in many different situations. From balancing accounts to making sense of a mobile phone bill, solving equations is a vital skill.

    • Solving simultaneous equations - AQA

      Algebraic skills are required to find the values of letters within two or more equations. If two or more equations have the same variables and solutions, then they are simultaneous equations.

    • Solving quadratic equations - AQA

      Solve quadratic equations by factorising, using formulae and completing the square. Each method also provides information about the corresponding quadratic graph.

    • Inequalities - AQA

      Inequalities show the relationship between two expressions that are not equal to one another. Inequalities are useful when projecting profits and breakeven figures.

    • Sequences - AQA

      Sequences can be linear, quadratic or practical and based on real-life situations. Finding general rules helps find terms in sequences.

    • Straight line graphs - AQA

      Graphs show the relationship between two variables and are often seen in newspapers and the media. People who work in professions involving maths and science commonly use graphs.

    • Other graphs - AQA

      The most commonly occurring graphs are quadratic, cubic, reciprocal, exponential and circle graphs. Their equations can be used to plot their shape.

    • Transformation of curves - Higher- AQA

      Functions of graphs can be transformed to show shifts and reflections. Graphic designers and 3D modellers use transformations of graphs to design objects and images.

    • Algebraic fractions - AQA

      Algebraic expressions in fraction form are rational. Methods of adding, subtracting, multiplying and dividing fractions plus expanding and factorising can be used to simplify rational expressions.

    • Using and interpreting graphs - AQA

      Using graphs is not just about reading off values. In real-life contexts, the intercept, gradient and area underneath the graph can have important meanings such as a fixed charge, speed or distance.
