Adding and Subtracting Integers

The video tutorial covers the addition of integers, focusing on both same and opposite signs. It begins with using a number line to visualize the addition of integers with the same sign, followed by rules and examples. The tutorial then shifts to adding integers with opposite signs, explaining the process using a number line and providing rules and examples. The video concludes with practical problems to reinforce the concepts.
