Every learner follows the same clear rhythm: learn the idea, see it worked through, practise it, then find out how you did.

Every exercise type below is available from your dashboard. Pick one to see how it works.
Drag a slider and watch the curve, gradient and roots respond in real time.
Sample
What happens to y = x² when you change it to y = x² + 3?
The whole curve shifts 3 units up.
Adding a constant outside the square moves every point up by that amount. Slide it yourself and watch the vertex hop from (0, 0) to (0, 3) — tricky ideas become obvious when you can move them.
Work through an equation one line at a time, with the reasoning shown at every step.
Sample
Solve 3x − 7 = 11. It looks harder than it is.
x = 6
Add 7 to both sides → 3x = 18. Divide both sides by 3 → x = 6. Every line is shown with its reason, so you always know why each move is allowed — no magic, just logic.
Short, focused drills that build fluency and instantly flag what to revisit.
Sample
60-second sprint: what is 17 × 6?
102
Split it: 10 × 6 = 60 and 7 × 6 = 42, then 60 + 42 = 102. Timed drills teach you these split-and-combine tricks until mental maths feels effortless.
Model solutions for every topic, with alternative methods side by side.
Sample
A £80 jacket is reduced by 25%. What is the sale price?
£60
Method 1: 25% of 80 is 20, so 80 − 20 = 60. Method 2: paying 75% means 0.75 × 80 = 60. Two routes, one answer — pick the one that clicks for you.
Weekly challenges and leaderboards against learners around the world.
Sample
Weekly challenge teaser: how many ways can you make 24 using 4, 6, 3 and 1 exactly once?
One way: 6 ÷ (1 − 3 ÷ 4) = 24. Can you find another?
