Exploring Adding and Subtracting Rational Expressions

This video tutorial covers integer operations including addition, subtraction, multiplication, and division. It explains the rules for handling integers with the same and different signs, and provides examples for each operation. Special cases such as the property of zero in multiplication and division are also discussed.
