Arithmetic Purpose and Tasks of Arithmetic The purpose of arithmetic is to teach students to consciously, rapidly, confidently, and rationally perform integer and fractional oral and written calculations. For this purpose, students should master the theory of natural numbers and fractions. The basic elements are: the nature of operations, the interdependence between computational structures, and the theory of the division of numbers. In addition to engaging in theory and calculation methods, students should also be good at establishing a variety of functional relationships between different quantities;
