# Addition and Subtraction of Integers: Rules, Examples

Comprehending the fundamentals of adding and subtracting whole numbers is crucial for being proficient in math and algebra. Whole numbers, which consist of zero, positive, and negative values, are called integers. This blog will walk you through the guidelines, offer illustrations, and help you understand these basic concepts.

1. Adding positive numbers: Just add the numbers in the same way as you would natural numbers.

Example: 4+8=12

1.  Adding negative numbers: Add the absolute values of the numbers and then add a negative sign to the result.

Example: (-4) +(-8) =-12

1. Adding a Positive and a Negative Integer: From the bigger absolute value, subtract the smaller absolute value. The number with the greater absolute value and the outcome have the same sign.

Example: (4) +(-8) =-4

Example: −5+9=4

### Rules for Subtracting Integers

1: Subtracting a Positive Integer

On the number line, you just move to the left when subtracting a positive integer.

Example: 10−3=7

2: Subtracting a Negative Integer

An integer's positive can be added while subtracting a negative integer.
Example: 6 −(−4)
Make the addition instead of the subtraction: 6 + 4 = 10

3: Subtracting a Positive Integer from a Negative Integer

Add the absolute values and maintain the negative sign when deducting a positive number from a negative number.

Example: −5−3

The result is −8

#### Example Problems

1. 15−6=9
2. 7−(−3) =10
3. −8−5

The result is −13

#### Conclusion

Anyone hoping to establish a solid mathematical foundation must comprehend and become proficient in the addition and subtraction of integers. These foundational abilities are essential for both improving mathematically and resolving practical issues including measurements, data analysis, and financial computations.

You may get a strong understanding of how to manage both positive and negative numbers in a variety of scenarios by adhering to the fundamental guidelines and practicing frequently. Recall that the secret is to proceed cautiously, follow the guidelines precisely, and double-check your work.

With further experience, these operations will become more natural to you, and handling integers will become a simple and doable chore. You'll quickly discover that addition and subtracting numbers comes naturally to you if you practice enough and have patience. Happy studying!
