## Study Notes

Integers are a fundamental concept in mathematics, formed by combining positive and negative whole numbers. These abstract values are used to represent both counting and measurement. Integers have a number of applications in various fields, including computer science, physics, economics, and engineering. In this article, we will explore the subtopics of addition, multiplication, properties, division, and subtraction of integers.

The addition of integers is a basic arithmetic operation. To add integers, you can follow these steps:

1. If the integers are positive, simply add their absolute values.
2. If the integers are negative, subtract their absolute values.
3. Keep track of the sign (positive or negative) of the integers.

For example, to add the integers 3 and 4, you would write:

3 + 4 = 7

If you want to add two negative integers, you would subtract their absolute values and keep the negative sign:

-3 + (-4) = -7

## Multiplication of Integers

Multiplication of integers is another fundamental operation. To multiply two integers, you can follow these steps:

1. Multiply the absolute values of the integers.
2. If the integers are both positive, the result is positive. If one or both are negative, the result is negative.

For example, to multiply the integers 3 and 4, you would write:

3 * 4 = 12

If you want to multiply two negative integers, you would multiply the absolute values and keep the negative sign:

-3 * (-4) = 12

## Properties of Integers

There are several properties of integers that are important to understand:

1. Commutativity: This property states that the order of the operands does not affect the result. In other words, a * b = b * a.
2. Associativity: This property states that the grouping of the operands does not affect the result. In other words, (a * b) * c = a * (b * c).
3. Distributivity: This property states that multiplication distributes over addition. In other words, a * (b + c) = (a * b) + (a * c).
4. Identity: There are two identity properties. The first states that any integer multiplied by 1 is the same integer. The second states that any integer multiplied by 0 is 0.
5. Inverse: Every non-zero integer has an inverse, which is another non-zero integer that, when multiplied with the original integer, results in 1.

## Division of Integers

Division of integers follows the same rules as division of other numbers. However, it is important to note that division by zero is not allowed in mathematics. When dividing two integers, you can follow these steps:

1. Divide the absolute values of the integers.
2. Keep track of the sign (positive or negative) of the integers.

For example, to divide the integers 10 and 2, you would write:

10 / 2 = 5

If you want to divide two negative integers, you would divide the absolute values and keep the negative sign:

-10 / -2 = 5

## Subtraction of Integers

Subtraction of integers is another basic arithmetic operation. To subtract integers, you can follow these steps:

1. If the integers are positive, subtract the smaller integer from the larger integer.
2. If the integers are negative, add their absolute values and keep the negative sign.

For example, to subtract the integers 3 and 4, you would write:

3 - 4 = -1

If you want to subtract two negative integers, you would add their absolute values and keep the negative sign:

-3 - (-4) = 7

In conclusion, integers are an essential concept in mathematics, and understanding the operations of addition, multiplication, properties, division, and subtraction is crucial for further study. These operations follow specific rules, and it is important to apply them correctly to solve mathematical problems and understand the underlying principles.
