Linear Relationships: When Change Is Constant
A linear relationship is one where two quantities change at a constant rate relative to each other. Straight lines on a graph, taxi meters, and electricity bills are all linear relationships in action.
Equations: Finding the Unknown
Equations are the engine room of mathematics — they let you find unknown values from what you already know. From splitting a dinner bill to launching a rocket, equations do the heavy lifting.
Indices: The Power Behind Exponential Growth
Indices are shorthand for repeated multiplication — and they're the reason compound interest, computer storage, and population growth all behave the way they do.
Algebraic Techniques: The Language of Generalisation
Algebra is the language of generalisation in mathematics. Instead of solving one specific problem, you solve infinitely many at once.
Ratios and Rates: The Maths of Comparison
Ratios and rates are everywhere — in recipes, maps, fuel consumption, and pay packets. Once you can read them fluently, a surprising amount of the world becomes easier to navigate.
Fractions, Decimals, and Percentages: Three Ways to Say the Same Thing
Three different ways to express parts of a whole — and understanding how they connect is one of the most useful things you can learn in maths.
What Are Integers — and Why Does Negative Numbers Even Make Sense?
Integers are the backbone of all mathematics — from temperatures and bank balances to GPS coordinates. Here's what they are, where they came from, and why they matter.
