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 वेळी एकच संकल्पना, एकच विचार, एकच दृष्टी, एकच दृष्टी, एकच दृष्टी, एकच संकल्पना, एकच विचार, एकच दृष्टी, एकच संकल्पना.

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.

कसे काम करते

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 पहा

एक नियम प्रत्येक टप्प्यात एक नियम - उत्पादन नियम, एक लाईन ऑपरेशन, एक यूक्लिडियन विभाग - एनिमेटेड आणि वाक्यात स्पष्ट केले.

3

त्याचा आकार बघा

Curves with their roots marked, surfaces you can rotate, triangles drawn to scale, factor trees, matrices as vectors in space.

4

अशक्य गोष्टीही

एक शब्द समस्या, एक सिद्धांत, एक खुला प्रश्न: शिक्षक त्याला तुम्ही हल्ले करू शकता अशा भागात विभागतो, तुम्हाला काय माहीत आहे ते सांगतो, आणि तुम्हाला हवे तेवढेपर्यंत तोडगा लपवतो.
