Integer Operations and Number Lines

This video tutorial covers the use of number lines to solve integer word problems. It explains how number lines can be both horizontal and vertical, and demonstrates their use in adding and subtracting integers. The tutorial includes examples of real-life applications, such as calculating money transactions, and emphasizes the importance of understanding integer operations before moving on to more complex topics. The video concludes with a preview of the next lesson on solving one-step equations.
