Solving quintic equations in terms of radicals (nth roots) was a major problem in algebra from the 16th century, when cubic and quartic equations were solved, until the first half of the 19th century, when the impossibility of such a general solution was proved with the Abel–Ruffini theorem.

Degree 4 – quartic (or, if all terms have even degree, biquadratic) Degree 5 – quintic; Degree 6 – sextic (or, less commonly, hexic) Degree 7 – septic (or, less commonly, heptic) Degree 8 – octic; Degree 9 – nonic; Degree 10 – decic; Names for degree above three are based on Latin ordinal numbers, and end in -ic.
In binary (base-2) math, multiplication by a power of 2 is merely a register shift operation. Thus, multiplying by 2 is calculated in base-2 by an arithmetic shift. The factor (2 −1) is a right arithmetic shift, a (0) results in no operation (since 2 0 = 1 is the multiplicative identity element), and a (2 1) results in a left arithmetic shift ...
Abel–Ruffini theorem refers also to the slightly stronger result that there are equations of degree five and higher that cannot be solved by radicals. This does not follow from Abel's statement of the theorem, but is a corollary of his proof, as his proof is based on the fact that some polynomials in the coefficients of the equation are not ...
The Chinese remainder theorem for polynomials implies that there is exactly one solution of degree less than = = (+). Moreover, this solution can be computed with O ( n 2 ) {\displaystyle O(n^{2})} arithmetic operations, or even faster with fast polynomial multiplication .

Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
