In this paper, we present new constructions of the n‐dimensional quadratic B‐splines method. The quadratic B‐splines method format is displayed in a single, two, and three‐dimensional format. These constructions are of utmost importance in solving differential equations in their various dimensions, which have applications in many fields of science. Some numerical examples are also presented, through which we can show the accuracy of this construction by giving some comparisons of our results using this new construction and between the results in other works. Some figures also give in this paper for the solutions.
