Positive and negative numbers are two types of real numbers that are used to represent values that are greater than or less than zero, respectively.

Positive numbers are represented by the plus sign (+), while negative numbers are represented by the minus sign (-). The number zero is neither positive nor negative.

Positive and negative numbers are used in a wide variety of applications, including mathematics, science, and engineering. They are also used in everyday life, such as when we measure temperature or money.

The concept of positive and negative numbers is essential for understanding many different aspects of the world around us. By understanding how positive and negative numbers work, we can better understand the world around us and make better decisions.

What Does a Positive and Negative Make

Positive and negative numbers are two types of real numbers that are used to represent values that are greater than or less than zero, respectively. They are used in a wide variety of applications, including mathematics, science, and engineering. Here are five key aspects of positive and negative numbers:

Addition and Subtraction: When you add two numbers with the same sign, the result is positive. When you add two numbers with different signs, the result is negative.
Multiplication and Division: When you multiply two numbers with the same sign, the result is positive. When you multiply two numbers with different signs, the result is negative.
Comparison: Positive numbers are greater than negative numbers. Zero is neither positive nor negative.
Absolute Value: The absolute value of a number is its distance from zero. The absolute value of a positive number is the number itself. The absolute value of a negative number is the opposite of the number.
Applications: Positive and negative numbers are used in a wide variety of applications, including mathematics, science, and engineering. They are also used in everyday life, such as when we measure temperature or money.

Positive and negative numbers are an essential part of mathematics and the real world. By understanding how they work, we can better understand the world around us and make better decisions.

Addition and Subtraction

This rule is a fundamental property of positive and negative numbers. It can be used to solve a variety of problems, such as finding the sum or difference of two numbers.

Adding two positive numbers: When you add two positive numbers, the result is always positive. This is because positive numbers are greater than zero, and when you add two positive numbers, you are essentially adding two values that are both greater than zero. For example, if you add 3 and 5, the result is 8, which is positive.
Adding two negative numbers: When you add two negative numbers, the result is always negative. This is because negative numbers are less than zero, and when you add two negative numbers, you are essentially adding two values that are both less than zero. For example, if you add -3 and -5, the result is -8, which is negative.
Adding a positive and negative number: When you add a positive and negative number, the result can be either positive or negative. The sign of the result depends on which number has the greater absolute value. For example, if you add 3 and -5, the result is -2, which is negative because the absolute value of -5 is greater than the absolute value of 3.

The rule for adding and subtracting positive and negative numbers is a powerful tool that can be used to solve a variety of problems. By understanding this rule, you can better understand the world around you and make better decisions.

Multiplication and Division

This rule is a fundamental property of positive and negative numbers. It can be used to solve a variety of problems, such as finding the product or quotient of two numbers.

Multiplying two positive numbers: When you multiply two positive numbers, the result is always positive. This is because positive numbers are greater than zero, and when you multiply two positive numbers, you are essentially multiplying two values that are both greater than zero. For example, if you multiply 3 and 5, the result is 15, which is positive.
Multiplying two negative numbers: When you multiply two negative numbers, the result is always positive. This is because negative numbers are less than zero, and when you multiply two negative numbers, you are essentially multiplying two values that are both less than zero. For example, if you multiply -3 and -5, the result is 15, which is positive.
Multiplying a positive and negative number: When you multiply a positive and negative number, the result is always negative. This is because when you multiply a positive number by a negative number, you are essentially subtracting the positive number from zero. For example, if you multiply 3 and -5, the result is -15, which is negative.

The rule for multiplying and dividing positive and negative numbers is a powerful tool that can be used to solve a variety of problems. By understanding this rule, you can better understand the world around you and make better decisions.

Comparison

The comparison of positive and negative numbers is a fundamental concept in mathematics. It allows us to determine the relative magnitude of two numbers and to order them accordingly. This concept is essential for understanding a wide range of mathematical operations, including addition, subtraction, multiplication, and division.

Positive numbers are greater than negative numbers because they represent values that are greater than zero. Negative numbers, on the other hand, represent values that are less than zero. Zero is neither positive nor negative because it represents the absence of any value.

The comparison of positive and negative numbers has a number of important applications in the real world. For example, it is used to compare temperatures, altitudes, and financial values. It is also used in a variety of scientific and engineering applications.

Understanding the comparison of positive and negative numbers is essential for understanding a wide range of mathematical and real-world concepts. By understanding this concept, we can better understand the world around us and make better decisions.

Absolute Value

The absolute value of a number is a measure of its distance from zero. It is always positive, regardless of whether the number is positive or negative. The absolute value of a number can be used to compare the relative magnitudes of two numbers. For example, the absolute value of -5 is 5, which is greater than the absolute value of -2, which is 2. This means that -5 is further away from zero than -2.

Positive Numbers: The absolute value of a positive number is the number itself. For example, the absolute value of 5 is 5.
Negative Numbers: The absolute value of a negative number is the opposite of the number. For example, the absolute value of -5 is 5.
Zero: The absolute value of zero is zero.

The absolute value of a number has a number of important applications in mathematics and the real world. For example, it is used to find the distance between two points on a number line, to compare the relative magnitudes of two numbers, and to solve equations and inequalities.

Applications

Positive and negative numbers are essential for understanding the world around us. They are used in a wide variety of applications, from mathematics and science to engineering and everyday life. Here are a few examples of how positive and negative numbers are used in the real world:

Mathematics: Positive and negative numbers are used in all branches of mathematics, from algebra to calculus. They are used to represent quantities that can be greater than or less than zero, such as temperature, velocity, and debt.
Science: Positive and negative numbers are used in all branches of science, from physics to chemistry. They are used to represent quantities that can be greater than or less than zero, such as temperature, charge, and energy.
