Adding And Subtracting Integers Worksheet With Answers
Table of Contents :
Adding and subtracting integers can be a challenging concept for many students, but with the right tools and practice, it becomes much easier to grasp. In this article, we will explore the intricacies of adding and subtracting integers, provide a comprehensive worksheet to reinforce learning, and include answers for self-assessment.
Understanding Integers
What Are Integers?
Integers are whole numbers that can be positive, negative, or zero. This means the set of integers includes numbers like -3, -2, -1, 0, 1, 2, and 3, and so forth.
The Importance of Integers
Understanding integers is essential because they are used in everyday situations, such as financial transactions, temperature changes, and even in computer science for data types.
Adding Integers
Adding integers is straightforward, but there are some important rules to remember:
-
Adding two positive integers results in a positive integer.
- For example, (3 + 5 = 8).
-
Adding two negative integers results in a negative integer.
- For example, (-2 + (-4) = -6).
-
Adding a positive integer to a negative integer: Subtract the smaller absolute value from the larger absolute value and keep the sign of the number with the larger absolute value.
- For example, (5 + (-3) = 2).
Examples of Adding Integers:
- (8 + 4 = 12)
- (-5 + (-7) = -12)
- (-6 + 2 = -4)
- (3 + (-8) = -5)
Subtracting Integers
Subtracting integers can be thought of as adding the opposite. Here’s how:
-
Subtracting a positive integer is the same as adding a negative integer.
- For example, (5 - 3 = 5 + (-3) = 2).
-
Subtracting a negative integer is the same as adding a positive integer.
- For example, (2 - (-4) = 2 + 4 = 6).
Examples of Subtracting Integers:
- (10 - 3 = 7)
- (-4 - (-2) = -4 + 2 = -2)
- (-6 - 4 = -10)
- (0 - 5 = -5)
