"Mastering Integers: Reteach Lesson 3 Subtraction Answers"

lesson 3 reteach subtract integers answers is a crucial topic in mathematics, particularly when it comes to understanding and applying the concept of subtracting integers. In this article, we will delve into the world of integers and provide a detailed explanation of lesson 3 reteach subtract integers answers, along with practical tips and examples to help you grasp this concept like a pro.

Understanding the Basics of Integers

Integers are whole numbers, either positive, negative, or zero. They are used to represent quantities that can be expressed without fractional parts. In the context of subtracting integers, it's essential to understand the concept of absolute value, which is the distance of a number from zero on the number line. For example, the absolute value of -3 is 3, and the absolute value of 5 is 5. When subtracting integers, we need to consider the sign of the numbers involved. If both numbers have the same sign (either both positive or both negative), we subtract their absolute values and keep the same sign. However, if the numbers have different signs, we subtract their absolute values and take the sign of the number with the larger absolute value.

Step-by-Step Guide to Subtracting Integers

Here's a step-by-step guide to subtracting integers:

1. Identify the signs of the numbers involved.
2. Subtract the absolute values of the numbers.
3. If the numbers have the same sign, keep the same sign for the result.
4. If the numbers have different signs, take the sign of the number with the larger absolute value.

Real-World Examples of Subtracting Integers

Let's consider a few examples of subtracting integers in real-world scenarios:

• Tom has -12 apples in his basket. His friend gives him 7 apples. How many apples does Tom have now?
• Jessica has 15 books on her bookshelf. She gives 3 books to her brother. How many books does Jessica have left?

To solve these problems, we need to subtract the integers involved. Using the steps outlined above, we can arrive at the correct answers.

Comparing the Results of Subtracting Integers

Let's compare the results of subtracting integers using a table:

Problem	Result
-12 - 7 =?	-19
15 - 3 =?	12

As you can see, the results of subtracting integers can be positive, negative, or zero, depending on the signs of the numbers involved.
