Don't just get the answer. See why.
SumClash Lab is SumClash's maths workshop. Type or snap any question and watch it worked out one step at a time, with the graph or picture beside it. Then learn the idea behind it, practise it, and ask Summy, our AI tutor, when you're stuck.

Who it's for
Students
Stuck on homework or revising for an exam? See every step of a solution, replay it, and ask why a step was done.
Teachers and parents
Show a class or a child how a problem is solved, one line at a time, with a picture to match.
Curious minds
Play with graphs, vectors, probability and calculus in labs you can drag and change.
What you can do in the Lab
Solve
- Ask anything: type a question or just a topic. Fractions to calculus, probability, finance, matrices and word problems all work.
- A full worked solution: what is being asked, the method, the working and a check, in clear stages.
- Pictures beside the working: graphs, number lines, figures and charts next to the step they belong to.
- Snap a question: take a photo of a question and Summy reads and solves it.
- Checked by the Lab engine: where it can, the Lab's own engine works the problem out and checks the answer.
Learn and practise
- Lessons: short step-by-step lessons and live graph lessons across arithmetic, algebra, geometry, trigonometry, calculus, statistics and more.
- Practice: fresh questions on a skill, and which skills you have mastered.
- Explore: interactive labs for calculus, transformations, complex numbers, statistics, vectors, mechanics, parametric and implicit curves.
Ask Summy
- Chat about any step: ask why a step was done, or what would change if the numbers changed. Chats are saved.
- Build a lab for a topic: name a topic and Summy builds a lab for it.
How it works
- Ask. Type a question or a topic, or snap a photo of one.
- Watch it solved. Step through the working one line at a time, with the picture beside it.
- Ask why. Open a step and ask Summy to explain it a different way.
- Practise. Try fresh questions on the same skill until it sticks.

Questions people ask first
What is the Lab for?
Understanding maths. It shows how a problem is solved, step by step, instead of only giving the answer, and lets you practise and explore the idea afterwards.
Can I ask a question that is not in the Lab?
Yes. The Lab solves what it knows itself, and Summy, our AI tutor, works out anything else. You need an account to ask.
Is the answer correct?
Where the Lab’s own engine can solve the problem, it works out and checks the answer itself. For other questions Summy writes the working and the engine checks it when it can. If the two disagree, the engine’s answer is shown.
Which topics are covered?
Arithmetic, algebra, geometry, trigonometry, calculus, statistics, probability, discrete maths, financial maths, word problems and advanced topics such as matrices, vectors and complex numbers.
Do I need to install anything?
No. The Lab runs in the browser on a phone, tablet or computer.
Is it free?
You can open one solution without an account, and a free account opens the rest. Summy answers have a daily allowance.
