Key Concepts in Adding and Subtracting Integers
Mastering integer operations involves understanding rules for adding and subtracting integers with the same or different signs, managing positive and negative values, and applying these principles to solve problems effectively.
2.1 Rules for Adding Integers with the Same Sign
When adding integers with the same sign, add their absolute values and keep the same sign. For example, 7 + 5 = 12, and (-3) + (-9) = -12. This rule applies to both positive and negative integers, simplifying calculations by focusing on magnitude and maintaining the sign.
2.2 Rules for Adding Integers with Different Signs
When adding integers with different signs, subtract the smaller absolute value from the larger and take the sign of the larger absolute value. For example, 8 + (-5) = 3, and (-12) + 7 = -5. This rule helps simplify calculations involving positive and negative integers.
2.3 Rules for Subtracting Integers
Subtracting integers involves adding the opposite. For example, 7 ‒ 3 = 4, and 7 ─ (-3) = 10. When subtracting a larger negative, like -5 ‒ 7, the result is -12. This method ensures accurate calculations with positive and negative integers in various combinations.
2.4 Understanding Positive and Negative Signs
Positive and negative signs dictate the direction of integers on the number line. A positive sign indicates a value to the right, while a negative sign points to the left. Recognizing these signs is crucial for accurate addition and subtraction, as they determine the outcome of operations involving both positive and negative integers.

Step-by-Step Guide to Solving Problems
Start by identifying the signs of the integers, then apply the appropriate addition or subtraction rules. Finally, verify your answers to ensure accuracy and understanding of the operations.
6.1 Identifying the Signs of Integers
Recognizing whether an integer is positive or negative is crucial. Positive integers are without a minus sign, while negative integers are preceded by a minus sign. This distinction determines the approach for addition and subtraction. Always note the signs before performing any operation to avoid errors in calculations.
6.2 Applying the Correct Operation
When adding or subtracting integers, it’s essential to apply the correct operation based on their signs. For integers with the same sign, add their absolute values and keep the sign. For different signs, subtract the smaller absolute value from the larger and take the sign of the larger. Subtraction involves adding the opposite, ensuring accurate results in calculations.
6.3 Checking Your Answers
Verifying your solutions ensures accuracy. Use estimation to check reasonableness or apply reverse operations. For addition, subtract the numbers to see if you return to the original values. For subtraction, add the result to the subtrahend to confirm the minuend. This method helps catch errors and builds confidence in your problem-solving skills.
Common Mistakes to Avoid
Common mistakes include mismanaging signs, incorrectly applying addition rules to subtraction, and not simplifying answers properly. These errors can lead to incorrect results, so careful attention is essential.
7.1 Mismanaging Positive and Negative Signs
Mismanaging positive and negative signs is a common error, leading to incorrect results. For example, (-7) + (-5) should be -12, not -2. Similarly, 3 + (-4) equals -1, not 7. Paying attention to signs ensures accurate calculations and prevents mistakes in integer operations.
7.2 Incorrectly Applying Addition Rules to Subtraction
A common mistake is using addition rules for subtraction, such as handling signs incorrectly. For example, subtracting a negative (-3 ─ (-4)) should be treated as addition (7), not doubled negatives. Similarly, changing all signs when subtracting differs from addition, so it’s crucial to apply the correct operation rules to avoid errors.
7.3 Not Simplifying Answers Properly
A common error is failing to simplify answers fully. For instance, leaving results like 7(-2) instead of -14 or not combining like terms properly. Always ensure final answers are in their simplest integer form. This avoids confusion and ensures accuracy in solutions, making it easier to verify correctness and understand the problem thoroughly.
