**E-learning Video Class 7 Maths - Integers in English**

A whole number, from zero to positive or negative infinity is called Integers. It is denoted by letter Z. On the number line, for positive integers we move to the right from zero and for negative integers move to the left of zero. If we add a positive integer, we go to the right. If we add a negative integer, we go to the left. If we subtract a positive integer, we go to the left. If we subtract a negative integer, we go to the right. This shows that the number which we add to a number to get zero is the additive inverse of that number.

For the closure property the sum of two integers must be an integer then it will be closed under addition.

As you can see that the addition of two integers will always be an integer, hence integers are closed under addition. If the difference between two integers is also an integer then it is said to be closed under subtraction.

As you can see that the subtraction of two integers will always be an integer, hence integers are closed under subtraction. If we change the order of the integers while adding then also the result is the same then it is said that addition is commutative for integers.

If we change the order of the integers while subtracting then the result is not the same so subtraction is not commutative for integers. If we change the grouping of the integers while adding in case of more than two integers and the result is same then we will call it that addition is associative for integers. If we add zero to an integer, we get the same integer as the answer.

So zero is an additive identity for integers. To multiply a positive integer with a negative integer, we can multiply them as a whole number and then put the negative sign before their product. To multiply two negative integers, we can multiply them as a whole number and then put the positive sign before their product. Hence, if the number of negative integers is even then the result will be a positive integer and if the number of negative integers is odd then the result will be a negative integer.

In case of multiplication, the product of two integers is always integer so integers are closed under multiplication. If we change the order of the integers while multiplying then also the result will remain the same then it is said that multiplication is commutative for integers. If we change the grouping of the integers while multiplying in case of more than two integers and the result remains the same then it is said the associative property for multiplication of integers.

The division is the inverse of multiplication.
