Mathematics is a branch of science that studies the world through numbers, quantities, shapes, and formulas. It involves the study of structure, space, quality, and change, and is used in many fields, including engineering, medicine, natural science, and social sciences.
Some key aspects of mathematics include:
Logical reasoning
Mathematics involves logical reasoning and quantitative calculation.
Abstract objects
Mathematics involves the description and manipulation of abstract objects, which can be abstractions from nature or purely abstract entities.
Proofs
Mathematics uses pure reason to prove properties of objects through a succession of deductive rules.
Branches
Some branches of mathematics include algebra, geometry, trigonometry, calculus, and number theory.
Mathematical description
A mathematical description is a system of postulates, data, and inferences that describes an entity or state of affairs.
Some common rules and formulas used in mathematics include:
BODMAS rule: This rule states that arithmetic operations are performed based on the order of operations and brackets.
Average formula: The average formula is Average = Sum of Values/ Number of values.
