The concept of fuzzy number, hybrid-differential equations, and delay-differential equations binds together to form our equations. An example following the algorithm is presented to understand the Concept of fuzzy hybrid retarded delay-differential equations and its accuracy is discussed in terms of decimal places for easy understanding of laymen.eninfo:eu-repo/semantics/openAccessHybridFuzzyRetarded DelayDifferential EquationsNumerical SolutionsFourth OrderRunge-Kutta MethodArticle10.3389/fphy.2019.001682-s2.0-85074698641
