Integers are a collection of whole numbers (0,1,2,3..) and their opposites (-1,-2,-3,-4..).

In this topic we will understand the properties of addition and subtraction of integers, like Commutative Law of Addition, which says that the two numbers can be added in any order--but this does not hold true for subtraction. Apart from this, we will study various other properties like Commutative Property, Associative Law, and that subtracting a negative is equivalent to adding a positive.

In this topic we will see what happens when we divide two integers and how their signs affect the result. For example, a negative divided by a negative gives a positive but a negative divided by a positive gives a negative.
