Arithmetic
A branch of mathematics dedicated to the rules of calculation in the set of rational numbers.
In arithmetic, we focus on the operations of addition, subtraction, multiplication, division and exponentiation (integer exponents). In addition to these basic operations, there are also factorials and absolute values. This discipline of mathematics was later extended by the inclusion of the study of real numbers in the form of unlimited decimal expansions. Then we added logarithmic and exponentiation (real exponents) operations.
