Class 7 Mathematics Chapter 1 Integers – Important Topics

Integers is a special set of numbers comprising zero, positive numbers and negative numbers. Integers are the collection of whole numbers and negative numbers. Similar to whole numbers, integers also does not include the fractional part. Thus, we can say, integers are numbers that can be positive, negative or zero, but cannot be a fraction. The examples of integers are, 1, 2, 5,8, -9, -12, etc. The symbol of integers is “Z“. 

There are five properties associated with Integers.

Closure Property: If m and n are two integers then the result that is generated will also be an integer. That is, m+n, m-n, and mn all three would be an integer.

Associative Property: Associative property of integers can be represented by, for integers p and q, r also results in an integer.

p+(q+r)=(p+q)+r

p× (q×r)=(p×q) ×r

Commutative Property: The commutative property of the integers in case of addition and multiplication defines that whatever be the order of integers in the operation, the result obtained will be the same, that is it will remain unchanged.

m+n = n+m

m×n = n×m

Distributive Property: According to the distributive property of integers, the operation can be performed over other operations within a bracket. 

p×(q+r)=p×q+q+r

p×(q-r)=p×q-p×r

Identity Property: According to the identity property, the additive identity property is when in addition zero is added to an integer, it yields the same integer.

m+0=0+m
