þáttunarleiðir
þáttunarleiðir is an Icelandic term that translates roughly to "methods of factorization" or "ways of decomposition." In mathematics, it refers to the process of breaking down a number or an expression into its constituent factors, which are typically smaller numbers or simpler expressions that, when multiplied together, yield the original entity. This concept is fundamental in various branches of mathematics, including number theory, algebra, and calculus.
In number theory, þáttunarleiðir primarily deals with the factorization of integers. The fundamental theorem of arithmetic
In algebra, þáttunarleiðir applies to the decomposition of polynomials and other algebraic expressions. This involves rewriting
