However, this comes at the cost of greater inequalities in the seats-to-votes ratio, which can violate the principle of one man, one vote. However, a greater concern for social choice theorists, and the primary cause behind its abandonment in many countries, is the tendency of such rules to produce erratic or irrational behaviors called ...
The Webster method, also called the Sainte-Laguë method (French pronunciation: [sɛ̃t.la.ɡy]), is a highest averages apportionment method for allocating seats in a parliament among federal states, or among parties in a party-list proportional representation system.
A solution of a linear system is an assignment of values to the variables ,, …, such that each of the equations is satisfied. The set of all possible solutions is called the solution set. [5] A linear system may behave in any one of three possible ways: The system has infinitely many solutions.
Chapter seven solves system of linear equations with two unknowns using the false position method, similar to The Book of Computations. [20] Chapter eight deals with solving determinate and indeterminate simultaneous linear equations using positive and negative numbers, with one problem dealing with solving four equations in five unknowns.

[1] [10] Of these countries, many do not use the zipper system evenly across legislative bodies, or have additional requirements. In France only bodies elected by proportional systems use the zipper system. [11] Zimbabwe uses the zipper system in Senate elections and only requires 60 out of the 80 seats apply the zipper system.

Rouché–Capelli theorem is a theorem in linear algebra that determines the number of solutions for a system of linear equations, given the rank of its augmented matrix and coefficient matrix. The theorem is variously known as the: Rouché–Capelli theorem in English speaking countries, Italy and Brazil;
Exact proportionality is never achieved under PR systems, except by chance. The use of electoral thresholds that are intended to limit the influence of small, extreme parties will reduce proportionality in list systems, and any insufficiency of leveling seats will further reduce proportionality in Mixed-member proportional or Additional-member systems.
The Kaczmarz method or Kaczmarz's algorithm is an iterative algorithm for solving linear equation systems =.It was first discovered by the Polish mathematician Stefan Kaczmarz, [1] and was rediscovered in the field of image reconstruction from projections by Richard Gordon, Robert Bender, and Gabor Herman in 1970, where it is called the Algebraic Reconstruction Technique (ART).
