Adding and Subtracting Integers

The video tutorial covers the addition and subtraction of integers, focusing on rules for handling integers with the same and different signs. It explains the process of subtracting integers with different signs by subtracting their absolute values and keeping the sign of the larger absolute value. For adding integers with the same signs, it emphasizes adding their absolute values and retaining the common sign. The tutorial uses number line examples to illustrate these concepts and concludes with practice problems to reinforce learning.
