Learn how to solve equations with brackets, 𝑥 terms on both sides, and fractions using inverse operations in this GCSE maths study guide. This guide contains videos and quizzes.

Inequalities are the relationships between two expressions not equal to one another. The symbols used for inequalities are <, >, ≤, ≥ and ≠. This guide contains video and quizzes.

This interactive quiz is suitable for GCSE maths students studying inequalities, solving inequalities, integer solutions to inequalities and graphs of inequalities.

Revise representing an inequality as a region on one side of a line. Dashed lines on graphs show the line is not included in the region. This guide contains video and quizzes.

Learn about term-to-term rules, 𝑛th term rules and how to work out expressions for 𝑛th terms based on a set of numbers in a quadratic sequence. This guide contains quizzes.

This interactive quiz is suitable for GCSE maths students studying using the nth term, finding the nth term of quadratic sequences, geometric sequences, and special sequences.

In geometric sequences, the term-to-term rule is to multiply or divide by the same value. Other sequences include square numbers and Fibonacci sequences. This guide has quizzes.

Revise translation and reflection of functions include cos(𝑥) and sin(𝑥) in this Higher tier maths guide. This guide contains a quiz and exam-style questions.

Simultaneous equations require algebraic skills to find the values of letters within two or more equations. They are called simultaneous equations because the equations are solved at the same time.

This interactive quiz is suitable for GCSE maths students studying simultaneous equations, and solving simultaneous examples with no common coefficients.

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

This interactive quiz is suitable for GCSE maths students studying solving quadratic equations by completing the square, and quadratic functions.

This interactive quiz is suitable for GCSE maths students studying finding roots by factorising, finding the turning point and the line of symmetry.

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

This interactive quiz is suitable for GCSE maths students studying quadratic graphs, cubic graphs, reciprocal graphs, exponential graphs.

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.

This interactive quiz is suitable for GCSE maths students studying real-life graphs, distance-time and displacement-time graphs, speed-time and velocity-time graphs.

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.

This interactive quiz is suitable for GCSE maths students studying simplifying rational expressions, factorising, and adding and subtracting rational expressions.
