'Adding and Subtracting Real Numbers' (PreAlgebra 1.3)

Adding and Subtracting Real Numbers: Understanding the Additive Inverse and Identity

In this video, we'll explore how to add and subtract real numbers by using number lines to visualize operations. We’ll also discuss the concepts of the additive inverse and additive identity and how they apply when working with integers, fractions, and decimals. By walking through several examples, you'll see how positive and negative numbers interact and learn the rules for combining real numbers.

What You Will Learn:
How to add and subtract real numbers using number lines.
Understanding the additive inverse and additive identity properties.
Strategies for dealing with negative and positive numbers in addition and subtraction.
Step-by-step examples with integers, fractions, and decimals.
