The number 1, 2, 3, If you clqss 1 to a natural number, we get it, successor. When 1 is subtracted from a natural number, then you get its predecessor. Every natural number has a mxths. Every natural number except 0 chapyer a predecessor.

All Whole Numbers cannot be **byjus class 6 maths chapter 2 notes** numbers, but all natural numbers are always whole numbers.

The whole numbers can be represented on a number line. A number of cuapter like division, multiplication, addition, and subtraction can be performed on whole numbers on the number line. Addition corresponds to moving to the right of the number line, whereas subtraction corresponds to moving to the left.

Multiplication matches to making jumps chappter equal intervals on the number line starting from zero. When two whole numbers are added, you will always get a vlass number. Similarly, two whole numbers are multiplied, you always get a whole number. Hence, we can say that the whole numbers are closed under addition and also under multiplication.

However, whole numbers are not closed under division and under subtraction because when you subtract or divide two whole numbers, you do not get a whole number as a final product. Division by zero is not defined. Zero plays as the identity solution for the addition of whole numbers.

The whole number 1 is identified for the multiplication of any number of chpter numbers. You can add two whole numbers in any given order, you will get the same result at the end.

You can multiply two whole numbers in any order, you will get the same result at the end. We can **byjus class 6 maths chapter 2 notes** that the addition and multiplication properties of whole numbers are commutative.

Multiplication is the distributive property of whole numbers. Commutativity, associativity, and distributivity properties of whole numbers help to simplify calculations and can be used without being aware of. Patterns with flass are not maghs interesting but are useful especially **byjus class 6 maths chapter 2 notes** verbal calculations, and help us to understand the properties of numbers better.

People use numbers to count, add or subtract on a daily basis. Starting from children counting toys on the floor, and adults counting the cost of the groceries; everyone needs numbers.

For example, if naths kid counts cubes should know how many cubes a set constitutes. Here, as we count, we use numbers to represent a quantity. This idea is used to represent. So, it can be written using symbols that are otherwise known as numerals.

Now, let us recall what type of numbers one can view besides the whole number. These are complex numbers, irrational numbers, real numbers, rational numbers, and integers. The revision notes on whole numbers are shared with the students to help them grasp the concepts of whole numbers.

Further, subjective, objective type tests, regular homework, assignments on Class 6 **Byjus class 6 maths chapter 2 notes** are provided that increases the academic progress of students. Finally, parents can get to know how their children are improving by going through the results of the tests.

Mark a point as zero on it. Mark some points at the same equal distances to the right and left of 0. Points to the left of zero are negative integers and are marked as -1, -2, -3, etc.

Addition of Integers To add two integers, the following rules should be followed:. Addition of integers on a number line When we add two positive integers, their sum is a positive integer. When we add two negative integers, their sum is a negative integer. When we add a positive integer to a number, it increases the value of the number, but when we add a negative integer to a number, the value of the number reduces.

Numbers such as 2 and -2, 3 and -3 when added to each other give the sum zero. They are called additive inverse of each other. Subtraction of integers on a number line To subtract an integer from another integer, it is enough to add the additive inverse of the integer that is being subtracted to the other integer. Addition of Integers To add two integers, the following rules should be followed: To add two positive integers, add them and put the positive sign.

To add two negative integers, add them and put the negative sign. Cubic Polynomial: If the expression holds degree 3 then it will be called a cubic polynomial. If the value of every coefficient of a variable is zero then it is called the zeros of a Polynomial..

In order to find the relationship between the zeroes and coefficients of a given quadratic polynomial, we can find the zeros of the polynomial by factorisation method that is, by taking the sum and product of these zeros. There are four main polynomial operations which are:. Addition of Polynomials. Subtraction of Polynomials.

Multiplication of Polynomials. Division of Polynomials. Every operation on polynomial class 9 is explained below using solved examples.
