What is a whole number?
Whole Numbers Definition. The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value.
What is the difference between natural and whole numbers?
Natural numbers are those which starts from 1 and ends at infinity, whereas whole numbers start from 0 and end at infinity. All the natural numbers are whole numbers but not all whole numbers are natural.
What are the properties of whole numbers?
The properties of whole numbers are: Whole numbers are closed under addition and multiplication. The addition and multiplication of whole numbers is commutative. The addition and multiplication of whole numbers is associative. It obeys the distributive property of multiplication over addition.
How to find the sum and product of two whole numbers?
The sum and product of two whole numbers will be the same whatever the order they are added or multiplied in , i.e., if x and y are two whole numbers, then x + y = y + x and x . y = y . x
What happens when a whole number is multiplied by 1?

What is natural number?
Natural numbers are the numbers starting from 1 and extend up to infinity. Counting numbers are used to count the objects or people or anything which is countable. Hence, we always start counting from 1. Test your knowledge on Whole Numbers.
What is the meaning of the set of whole numbers?
And it isn’t only one thing. The set of whole numbers is what we call “countably infinite”, meaning that we can put its elements into a single list that contains all the elements exactly once each.
What is the difference between rational and irrational numbers?
A rational number is a number which you can present as a fraction of a/b while a and b are integers, and b≠0. An irrational number is a number that there aren’t any a and b for it so that it equals a/b while a and b are integers, and b≠0.
What is a complex number with a non zero imaginary part?
A complex number with a NON-ZERO imaginary part is denoted as a pure imaginary number.
What happens when the imaginary part of a complex number is zero?
But when the imaginary part of a complex number is zero, the rotation of the complex axis also results in zero. Thus we get the axis with the real numbers. This means we have eradicated the imaginary part of the number.
Where are complex numbers found?
Geometrically complex numbers are presented perpendicular to the real axis as they are found on the vertical axis of the complex number plane. And a complex number plane is a modified version of cartesian where the complex number is found on the z axis (also perpendicular to the real axis).
Is a whole number a real number?
So, whole number's set is also the subset of the real number's set. So, all whole numbers are real numbers but all real numbers need not be the whole numbers.
Do rational numbers integrate with transcendental numbers?
Rational numbers do not integrate precisely with transcendental numbers, therefore numbers exist in mind only.
What is a whole number?
Whole numbers include natural numbers that begin from 1 onwards. Whole numbers include positive integers along with 0. There is no 'largest' whole number. Except 0, every whole number has an immediate predecessor or a number that comes before.
Does every whole number have an immediate predecessor?
Except 0, every whole number has an immediate predecessor or a number that comes before.
What is real number?
Real Numbers. Real numbers are simply the combination of rational and irrational numbers, in the number system. In general, all the arithmetic operations can be performed on these numbers and they can be represented in the number line, also. At the same time, the imaginary numbers are the un-real numbers, which cannot be expressed in ...
What are the properties of real numbers?
The four main properties of real numbers are commutative property, associative property, distributive property and identity property. Consider “m, n and r” are three real numbers. Then the above properties can be described using m, n, and r as shown below:
What are some examples of rational numbers?
Examples of rational numbers are ½, 5/4 and 12/6 etc. Irrational Numbers. All the numbers which are not rational and cannot be written in the form of p/q. Irrational numbers are non-terminating and non-repeating in nature like √2.
What is imaginary number?
At the same time, the imaginary numbers are the un-real numbers, which cannot be expressed in the number line and is commonly used to represent a complex number. The concepts related to real numerals are explained here in detail, along with examples and practice questions.
Is a real number irrational?
No, there are no real numbers that are neither rational nor irrational. The definition of real numbers itself states that it is a combination of both rational and irrational numbers.
Is a real number a natural number?
All the natural numbers are integers but not all the integers are natural numbers. These are the set of all counting numbers such as 1, 2, 3, 4, 5, 6, 7, 8, 9, …….∞. Real numbers are the numbers which include both rational and irrational numbers.
What is natural number?
The natural numbers (also known as counting numbers) are the numbers that we use to count. It starts at 1, followed by 2, then 3, and so on. The whole numbers are a slight “upgrade” of the natural numbers because we simply add the element zero to the current set of natural numbers.
What are some examples of real numbers?
The set of whole numbers includes the number zero and all natural numbers. This is a true statement. Example 2: An integer is always a whole number. The set of integers is composed of the number zero, natural numbers, and the “negatives” of natural numbers.
What happens when you pour water into the funnel of natural numbers?
If we pour water into the “funnel of natural numbers”, the water should also flow through all the funnels below it. Thus, passing through the funnels of the whole numbers, integers, and rational numbers. Example 6: Every whole number is a natural number, integer, and a rational number.
What is a set of integers?
The set of integers is composed of the number zero, natural numbers, and the “negatives” of natural numbers. That means some integers are whole numbers, but not all. For instance, − 2. - 2 −2 is an integer but not a whole number. This statement is false. Example 3: Every rational number is also an integer.
Is zero a real number?
Definitely not a natural number but it is a whole, an integer, a rational, and a real number. It may not be obvious that zero is also a rational number. However, writing it as a fraction with a nonzero denominator would clearly show that it is indeed a rational number.
Is the fraction large a rational number?
The fraction Large {1 over 2} is an example of a rational number that is NOT an integer. So this statement is false.
Is a real number rational or irrational?
The irrational numbers are all numbers which when written in decimal form do not repeat and do not terminate. The real numbers include both rational and irrational numbers.
What is a real number?
A real number is any number on the number line and includes subsets of numbers including natural, whole, integer, rational and irrational numbers. In simpler terms, all numbers are real numbers except for imaginary numbers—which are a set of complex numbers once thought to be impossible to calculate.
What is an irrational number?
An irrational number is a real number that you cannot write as a simple fraction. Numbers that you cannot write as a fraction are decimals that go on forever with no repeating pattern.
What is an integer?
An integer is a positive or negative whole number with no fractional or decimal part. Integers are a subset of real numbers and include the subset's whole number and natural numbers. It's common for integers to be represented as: "-3, -2, -1, 0, 1, 2, 3" as this shows the numbers are infinite in either direction, whole numbers and contain the number zero.
Can integers include fractions?
Real numbers can include fractions due to rational and irrational numbers, but integers cannot include fractions.
Where are integers on the number line?
Integers are positive, so you see them on the right side of the number line and positive integers have a higher value than their negative counterparts or opposites.
Is integer a real number?
Integers are real numbers, but not all real numbers are integers. Here are some differences:
Is pi a decimal?
The number pi, or "π," is an irrational number because it is a decimal that goes on forever without repeating and you cannot write it as a fraction.
