The reciprocal addition formula obtained is proven by using the Fibonacci number identities, the properties of the Fibonacci numbers, and algebraic calculations. This article is a review of some of Wang and Liu’s articles [Advances in Difference Equations, 136 (2016), 1-26].enFibonacci numbersreciprocalfloor functionArticle
