In mathematics, numbers are used to quantify and measure objects and quantities. They are classified into different types such as natural numbers, whole numbers, integers, rational numbers, and irrational numbers.

Natural numbers are the counting numbers, which start from 1 and go up to infinity. They are represented as N = {1, 2, 3, 4, ...}.

Whole numbers include all the natural numbers along with the number 0. They are represented as W = {0, 1, 2, 3, 4, ...}.

Integers include all the whole numbers along with their negative counterparts and zero. They are represented as Z = {..., -3, -2, -1, 0, 1, 2, 3, ...}.

Rational numbers are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. They can be represented as a/b, where a and b are integers and b ≠ 0.

Irrational numbers are numbers that cannot be expressed as a fraction of two integers. They are non-repeating and non-terminating decimals. Examples include √2, π, and e.

Basic operations with numbers include addition, subtraction, multiplication, and division. These operations follow specific rules and properties.

- Practice identifying different types of numbers.
- Understand the properties of each type of number.
- Practice performing operations with different types of numbers.
- Memorize common irrational numbers and their decimal approximations.
