The contribution of Arabic mathematics

Arabs' contribution to ancient mathematics is the most familiar number 1, 2, ... 9, 0, which is the so-called Arabic numeral. However, during the development of mathematics, Arabs mainly absorbed and preserved the mathematics of Greece and India and spread it to Europe, thus building a "bridge of mathematics".

Numeric symbols and carry symbols

The Arabs adopted and improved India's numerical notation and carry notation, adopted India's mathematical notation and carry notation, and adopted India's irrational number operation, but gave up the negative number operation.

Algebra discipline

The name algebra was invented by Arabs.

Geometric solution

Arabs have also solved some linear, quadratic or even cubic equations and explained their solutions with geometric figures.

Accurate pi

The Arabs also got a more accurate pi, 2π = 6.28185307195865, and π was calculated to 17.

Triangle sine law

Arabs also introduced the tangent and cotangent of triangles and proved the sine law of planar triangles. They also put forward a relatively complete theory of plane triangle and spherical triangle.

Translation and Writing of Mathematical Literature

As a "bridge of mathematics", Arabic mathematics also lies in translating and writing a large number of mathematical documents. After these works spread to Europe, mathematics entered a new development period.
