Learn all of maths, in order.

From counting to the open problems. Pick where you are; every lesson shows its steps, draws the picture, and hides the answer until you ask.

Or bring your own problem

Type it, or draw it with your mouse or finger. Equations, derivatives, matrices, triangles, primes — or a word problem the tutor breaks into parts.

What each stage covers

प्रत्येक एक एक जीवित काम उदाहरण संग पाठ को एक सेट छ, एक दृश्य, र एक Solver यो लागि tune.

Stage 1 Arithmetic Numbers, fractions, percentages and the order of operations. Stage 2 Algebra Equations, inequalities, factoring, functions and systems. Stage 3 Geometry Triangles, circles, polygons, solids and coordinates. Stage 4 Trigonometry Angles, the unit circle, identities and trig equations. Stage 5 Precalculus Functions in depth, complex numbers, sequences, conics and vectors. Stage 6 Calculus Limits, derivatives, integrals, series and optimisation. Stage 7 Linear Algebra Matrices, determinants, inverses, row reduction and eigenvalues. Stage 8 Statistics & Probability Averages, spread, counting and probability. Stage 9 Discrete Math & Logic Counting, logic, truth tables, sets and proof. Stage 10 Number Theory Primes, divisibility, gcd, modular arithmetic and sequences. Stage 11 Differential Equations Equations whose unknown is a function: growth, oscillation, and how physics is written. Stage 12 Analysis Limits made rigorous: sequences, series, convergence, improper integrals, complex numbers as functions. Stage 13 Frontiers The open problems — Riemann, Navier–Stokes, P vs NP — broken into what you need to even read them.

यो कसरी काम गर्दछ

1

Type it or draw it

“derivative of x² sin x”, “is 561 prime”, “triangle 3 4 5” — or sketch the equation on the pad and it is read for you.

2

प्रत्येक चाल हेर्नुहोस्

एक नियम प्रति चरण — उत्पादन नियम, एक पङ्क्ति सञ्चालन, एक यूक्लिड विभाजन — जीवित, र एक वाक्य मा व्याख्या।

3

यसको आकार हेर्नुहोस्

तिनको मूलहरू चिन्ह लगाइएको वक्रहरू, तपाईँले घुमाउन सक्नुहुन्छ सतहहरू, मापन गर्न रेखाङ्कित त्रिकोणहरू, तत्व ट्रीहरू, खाली स्थानमा भेक्टरहरूको रूपमा म्याट्रिक्सहरू ।

असम्भवहरू पनि

शब्द समस्या, एक प्रमाण, एक खुला प्रश्न: शिक्षक तपाईं आक्रमण गर्न सक्छन् भागहरूमा यो तोड्छ, के ज्ञात छ तपाईंलाई बताउँछ, र तपाईं यसलाई चाहनुहुन्छ सम्म समाधान लुकाउँछ।
