Branches of science
"Mathematics", first of all known as The Science of numbers which is classified in Arithmetic and Algebra, is classified as a formal science, has both similarities and differences with the empirical sciences (the natural and social sciences). It is similar to empirical sciences in that it involves an objective, careful and systematic study of an area of knowledge; it is different because of its method of verifying its knowledge, using "a priori" rather than empirical methods.
