In this article, we will elaborate on the rules of adding integers, provide examples that are relevant, and provide insights on becoming proficient in the concept. We will also describe how 98thPercentile can assist students in learning math with an innovative approach. 

What are Integers? 

Integers are those numbers that are either negative, positive, or zero but are not composed of a decimal or a fraction. Integers are symbolised as a: 

Integers (Z) = {...., –3, –2, –1, 0, 1, 2, 3, ....} 

Examples of Integers  

• Positive integers: 1, 2, 3, 4, 5, 6 

• Negative integers: –1, –2, –3, –4, –5, –6 

• Zero: 0 

Why is Adding Integers Important? 

Addition of integers is an important math skill as it can be applied in life to calculate temperatures, bank accounts (credits and debits), and game scores. Knowing the rules of addition integers is what ensures accuracy in such a situation and is the base for other complicated mathematical concepts. 

Rules for Adding Integers 

When you add integers, there are some rules following whether the integers possess the same or opposite sign. Let me spell it out below: 

1. Sum of Two Positive Integers 

When two positive integers are to be added up: 

• Just sum their absolute values. 

• The result is always favourable.  

Example:

5 + 8 = 13 

2. Adding Two Negative Integers

When adding two negative integers:  

• Take their absolute values. 

• The outcome will always be negative. 

Example: 

(–5) + (–8) = –13 

3. Sum of a Positive Integer and a Negative Integer

When we have integers of opposite signs: 

• Subtract the lesser absolute value from the larger absolute value. 

• The result bears the sign of the integer with the larger absolute value. 

Example: 

5 + (–8) = –3 

4. Introducing an Integer to Zero

Adding zero to any number results in the same number. 

Example: 

The integer addition rules below table explains the concept in a practical manner for a better understanding: 

Steps to Add Integers 

Just follow these simple steps to add integers successfully: 

1. Find Absolute Values: Determine the absolute values of the given integers.

2. Check Signs: Check if the integers are both positive or negative.  

3. Do Operation:  

• Take their absolute values and have the same sign in case they share the same sign. 

• If they are of opposite signs, take their absolute values and place the sign of the larger number.  

4. Check Answer: Double-check arithmetic to be certain. 

Real-Life Applications of Integers 

Adding integers isn't merely an exercise in mathematics - it's applied to many real-life situations: 

1. Banking: Positive values denote deposits, while negative values denote withdrawals. For instance: 

Balance: 500 dollars 

Withdrawal: –200 dollars 

Total: 500 + (−200) = 300 

3. Sports Scores: In sports such as golf or hockey, scores are positive or negative depending on performance.
4. Temperature Fluctuations: Positive values indicate increasing temperatures, and negative values indicate decreasing temperatures.
   

Tips for Mastering Integer Addition 

Below are some strategies to help students become proficient at adding integers: 

1. Use Number Lines: Imagine integer addition on the number line by going right for positive integers and left for negative integers.  

2. Practice with Real-Life Examples: Encourage students to apply integer addition to real-life contexts such as balancing allowance or score. 

3. Memorize Rules: Remembering addition facts helps students to respond faster on homework or tests.

4. Solve Step-by-Step Problems: Break down complicated problems into steps so that they're simpler to compute.
