Numbers (mathematics)

Numbers are fundamental symbols used to represent quantities and values in mathematics. They can be classified into various types, such as whole numbers, integers, rational numbers (fractions), and irrational numbers (like π). Numbers facilitate counting, measuring, and performing calculations. They form the basis for mathematics and are essential in daily life, science, engineering, and technology. Additionally, concepts such as place value (the value of a digit based on its position) and operations like addition, subtraction, multiplication, and division are key to understanding how numbers interact and can be manipulated.
