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

ທຸກໆອັນແມ່ນຊຸດຂອງບົດຮຽນທີ່ມີຕົວຢ່າງທີ່ເຮັດວຽກ, ພາບ, ແລະ ວິທີແກ້ໄຂທີ່ປັບແຕ່ງໃຫ້ມັນ.

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.

ວິທີການ​ເຮັດວຽກ

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

ເບິ່ງ​ທຸກ​ການ​ເຄື່ອນ​ໄຫວ

ກົດລະບຽບ​ໃນ​ແຕ່ລະ​ບາດກ້າວ​ - ກົດລະບຽບ​ຂອງ​ຜົນ​ຜະລິດ, ​ການ​ປະຕິບັດ​ການ​ແຖວ, ການ​ແບ່ງ​ Euclid - ເຄື່ອນໄຫວ, ແລະ​ອະທິບາຍ​ໃນ​ຄໍາ​ສັບ​ຫນຶ່ງ.

ເບິ່ງຮູບຮ່າງຂອງ​ມັນ

ເສັ້ນໂຄ້ງ​ທີ່​ມີ​ຮາກ​ຂອງ​ພວກ​ມັນ​ຖືກ​ສະ​ແດງ​ໃຫ້​ເຫັນ, ພື້ນ​ທີ່​ທີ່​ສາມາດ​ປັ່ນ​ໄດ້, ສາມຫຼ່ຽມ​ທີ່​ໄດ້​ແຕ້ມ​ເພື່ອ​ຂະ​ໜາດ, ຕົ້ນ​ປັດໃຈ, ມາດິດ​ທີ່​ເປັນ​ເວັກ​ເຕີ​ໃນ​ພື້ນທີ່.

4

ສິ່ງ​ທີ່​ບໍ່​ເປັນ​ໄປ​ໄດ້​ອີກ​ດ້ວຍ

ບັນຫາ​ຄຳ, ຫຼັກຖານ, ຄໍາຖາມ​ເປີດ: ຜູ້ສອນ​ຈະ​ແບ່ງ​ມັນ​ອອກ​ເປັນ​ສ່ວນ​ທີ່​ທ່ານ​ສາມາດ​ໂຈມຕີ, ເວົ້າ​ກັບ​ທ່ານ​ວ່າ​ທ່ານ​ຮູ້​ຫຍັງ ແລະ ​ປິດ​ການ​ແກ້ໄຂ​ຈົນ​ກວ່າ​ທ່ານ​ຈະ​ຕ້ອງການ​ມັນ.
