Working with fractions
Fractions describe parts of a whole. Here you can see how to calculate with them and why a common denominator helps.
Open the guide Lower and upper secondaryPercentages
A discount, a price increase or a change over time: start by distinguishing the part, the whole and the percentage.
Open the guide Lower and upper secondarySolving equations
An equation says that two expressions are equal. The aim is to find the unknown number while keeping the balance.
Open the guide Lower and upper secondaryLinear functions
A function describes a relationship. For a straight line, k gives the slope and m gives where the line crosses the y-axis.
Open the guide Lower and upper secondaryPowers
A power is a short way of writing repeated multiplication. Here you can get to grips with exponents and the rules that go with them.
Open the guide Lower secondary and revisionArea, volume & Pythagoras
Start with the shape and what the problem asks for. Here you will find methods for area, volume and the sides of a right-angled triangle.
Open the guide Upper secondary · selected topicsSquaring identities
Recognising the pattern in an expression makes it easier to expand or factorise it. Here you can see the rules in use.
Open the guide Upper secondary · further topicsDerivatives
Derivatives help you describe how quickly something changes. Start with rates of change and continue with differentiation rules.
Open the guide Upper secondary · selected topicsSin, cos & tan
Trigonometry connects angles and side lengths. Here we move from right-angled triangles to the unit circle and triangle rules.
Open the guide Upper secondary · algebraQuadratic equations
A quadratic equation contains x². Here you choose a method, follow the calculation and check the solutions. Start with the examples, then try three problems yourself.
Open the guide Upper secondary · powers and logarithmsLogarithms
A logarithm answers the question: which exponent is needed? Here we connect logarithms to powers and use them when the unknown variable is in the exponent.
Open the guide Lower secondary and revisionStatistics
Which number best describes a group of values? Mean, median and mode show different things. Here we use the same example and see what happens when one value stands out.
Open the guide Lower and upper secondaryProbability
How likely is something to happen? Start with possible outcomes, then move on to several events. The examples show when you can multiply and when the probability changes.
