Abstract:  In this paper, we examine the product rule and the arithmetic derivative. We first find a closed-form formula for the arithmetic derivative over positive integers. We then extend the argument to negative numbers, rational numbers, power roots, and complex numbers. Throughout our research, we also use Mathematica graphics to help visualize the behavior of the arithmetic derivative over different domains and explore boundary conditions and intermediate lines. Finally, we discuss the continuity of arithmetic derivative and give a continuous form that satisfies the product rule.Please click on this link to an accessible Google doc to read the paper, including equations, graphs, images, and data charts:
