Nature is characterized by its chaotic behavior. Mathematics is considered one of the appropriate tools to achieve the best definition of possible its chaos variables and process. Classical mathematics deals with the numbers as static and meaningless, but chaos mathematics deals with it as dynamic evolutionary, and value- added. This paper attempts to introduce the transportation problem re...

this paper is about concept maps and how they can assist in the learning ofconcepts of mathematics. first the paper presents the theoretical backgroundand working denitions for concept maps. then this study examines the impactof using concept maps in learning of fractions. results of this study indicatedthat using this strategy was eective in learning of fractions for fourth-gradestudents. th...

in this paper some algebraic structures for linguistic fuzzy models are defined for the first time. by definition linguistic fuzzy norm, stability of these systems can be considered. two methods (normed-based & graphical-based) for stability analysis of linguist fuzzy systems will be presented. at the follow a new simple method for linguistic fuzzy numbers calculations is defined. at the end tw...
