How to Calculate Negative Integer

What is a Negative Integer?

A negative integer is a whole number that is less than zero. The set of negative integers includes numbers like -1, -2, -3, and so on. These numbers are distinct from positive integers (1, 2, 3, ...) and zero.

Negative integers are used to represent quantities that are below a reference point, such as temperatures below freezing, financial debts, or positions below sea level. They are essential in various mathematical operations and real-world applications.

How to Calculate with Negative Integers

Working with negative integers involves understanding the rules of arithmetic operations. Here are the basic rules:

• Addition: Adding two negative integers results in a negative integer. For example, -3 + (-2) = -5.
• Subtraction: Subtracting a negative integer is the same as adding its positive counterpart. For example, -5 - (-3) = -5 + 3 = -2.
• Multiplication: Multiplying two negative integers results in a positive integer. For example, -4 × -3 = 12.
• Division: Dividing two negative integers results in a positive integer. For example, -12 ÷ -3 = 4.

Common Operations with Negative Integers

Negative integers are used in various mathematical operations. Here are some common examples:

Real-World Examples

Negative integers are used in various real-world scenarios:

• Temperature: A temperature of -5°C is 5 degrees below freezing.
• Finance: A bank balance of -$100 indicates a debt of $100.
• Elevation: A depth of -100 meters is 100 meters below sea level.
