Real numbers can be shown on the number line.The collection of real numbers is made by all rational and irrational numbers.Some important points related to Real Numbers include: Non-terminating and non-repeating numbers such as √2 The numbers are not rational and can’t be written in the p/q form. Numbers that can be written in the p/q form, where q≠0.Įxamples of rational numbers are ½, 5/4 and 12/6, etc. For example, 4, 6, 8, 9, 10 etc.Īll numbers comprising 0 such as 0, 1, 2, 3, 4, 5, 6,….…Ĭombination of Whole numbers and negative of all the natural numbers. 1 does not belong to prime numbers as well as composite numbers. Composite numbers: Composite numbers are natural numbers that are divisible by 1, itself as well as any other integer or number.1 is not a prime number because it has only one factor. Prime numbers have two factors: 1 and the number itself.
Prime numbers: Prime numbers are natural numbers higher than 1 that are divisible by 1 and the number itself.Examples include 1, 3, 5, 7, and so forth. We obtain a remainder when we divide an odd integer by two. It cannot be divided evenly into two separate integers. Odd numbers: Odd numbers are numbers that cannot be divided by two in an exact manner.Even numbers always end up with 0, 2, 4, 6, or 8 in the last digit. Even numbers: Even numbers are integers that are divisible by 2.Irrational numbers: All numbers that can not be expressed in the form of p/q are known as irrational numbers.Integers: All positive and negative numbers (not fractions) including zero are called the Integers.Whole Numbers: The set of all the natural numbers and zeroes are called whole numbers.Natural Numbers: All Counting numbers starting with one are called natural numbers.Rational Numbers: The numbers that can be written in the form of p/q where p and q are both integers and q ≠ 0. Rational Numbers can be further divided into.Real numbers are divided into two main categories i.e. Among all the other numbers √-8 is a complex number so it cannot be a real number.Īll the other numbers are either rational or irrational numbers. Find the real numbers among √7, √-8, ⅔, -6.Īns.
