HSC Higher Mathematics 2nd Paper Question 2018 Rajshahi, Cumilla, Chattogram, Barishal Board. Mathematicians seek patterns and formulate new conjectures. Mathematicians solve the truth or falsity of conjectures by mathematical proof. The research needed to solve mathematical problems can take years, or even centuries of investigation supported. Since the pioneering work of Giuseppe Peano (1858-1932), David Hilbert (1862-1943), and others on the axiomatic systems by the end of the 19th century, it became customary to show that mathematical research establishing the truth by rigorous deduction from axioms of appropriately chosen and definitions. When these structures are good mathematical models of real phenomena, mathematical reasoning can give an overview or predictions on nature.

The research needed to solve mathematical problems can take years, or even centuries of investigation supported.

Mathematics has no generally accepted definition. Aristotle defined mathematics as “the science of quantity” and this definition prevailed until the 18th century. In the 19th century, when the study of mathematics increased in rigor and began to address abstract topics such as group theory and projective geometry, which have no clear-cut relation to quantity and measurement, mathematicians and philosophers began to propose a variety of new definitions.

An early definition of mathematics in terms of logic was Benjamin Peirce’s “the science that draws necessary conclusions” (1870). In the Principia Mathematica, Bertrand Russell and Alfred North Whitehead advanced the philosophical program known as logicism and attempted to prove that all mathematical concepts, statements, and principles can be defined and proved entirely in terms of symbolic logic. A logicist definition of mathematics is Russell’s “All Mathematics is Symbolic Logic” (1903).

Intuitionist definitions, developing from the philosophy of mathematician L. E. J. Brouwer, identify mathematics with certain mental phenomena. An example of an intuitionist definition is “Mathematics is the mental activity which consists in carrying out constructs one after the other.” A peculiarity of intuitionism is that it rejects some mathematical ideas considered valid according to other definitions. In particular, while other philosophies of mathematics allow objects that can be proved to exist even though they cannot be constructed, intuitionism allows only mathematical objects that one can actually construct. Intuitionists also reject the law of excluded middle — a stance that forces them to reject proof by contradiction as a viable proof method as well.

Formalist definitions identify mathematics with its symbols and the rules for operating on them. Haskell Curry defined mathematics simply as “the science of formal systems”.[46] A formal system is a set of symbols, or tokens, and some rules on how the tokens are to be combined into formulas. In formal systems, the word axiom has a special meaning different from the ordinary meaning of “a self-evident truth”, and is used to refer to a combination of tokens that is included in a given formal system without needing to be derived using the rules of the system.
