### Basics of integers review

Let's recall some of the things we have learnt about integers in earlier classes like how to add and subtract negative numbers and what the additive inverse (number opposite) is.

### Properties of addition and subtraction of integers

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.

### Multiplication of integers

In this section we will see what happens when we multiply two integers, and how their signs affect the result. For example, a negative times a negative is a positive but positive times a negative is a negative.

### Properties of multiplication of integers

In this section, we will understand the fundamental laws of Multiplication like Commutative Law which says that integers can be multiplied in any order; Identity property of 1 which says that an integer multiplied with 1 gives the same integer. Apart from this we will study various other laws like Associative Law, Combining like terms, and the Distributive Property

### Division of integers

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.
