Types of Numbers in Math
There are three types of numbers in math: natural numbers, integers, and rational numbers.
The natural numbers are the counting numbers: 1, 2, 3, 4, 5, etc.
Integers are the whole numbers: 0, 1, 2, 3, 4, 5, etc.
Rational numbers are numbers that can be expressed as a fraction, with a numerator and a denominator. For example, 1/2, -3/4, and 5 are all rational numbers.

What Are Numbers?
Numbers are symbols that represent quantities. We use numbers to count things, to measure things, and to calculate things.
Numbers in Real Life
Numbers are used in everyday life to measure, calculate, and record information. For example, when grocery shopping, a customer might use numbers to keep track of the items they are buying and the total cost. In a business, numbers might be used to track sales, profits, and expenses. In school, students might use numbers to solve math problems or to record test scores. Numbers can be used in a variety of ways to help make everyday tasks easier.
Classification of Numbers
Natural numbers are numbers that can be counted, such as 1, 2, 3, 4, and so on.
Integers are natural numbers and their opposites, such as 0, 1, -2, and so on.
Rational numbers are numbers that can be expressed as a quotient of two integers, such as 1/2, -4/3, and so on.
irrational numbers are numbers that cannot be expressed as a quotient of two integers, such as π and √2.
Different Types of Numbers
Natural Numbers:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100
Integers:
All natural numbers, including 0.
Positive Integers:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36
Quantum Numbers
There are four quantum numbers:
n, the principal quantum number
l, the orbital quantum number
ml, the magnetic quantum number
ms, the spin quantum number
Types of Quantum Numbers
The four types of quantum numbers are:
The principal quantum number, n, which specifies the energy level of the electron.
The angular momentum quantum number, l, which specifies the shape of the electron’s orbit.
The magnetic quantum number, m, which specifies the orientation of the electron’s orbit.
The electric quantum number, ms, which specifies the spin of the electron.
