Understanding Negative Numbers and Operations

Rachel explains how to perform basic arithmetic operations with negative numbers. She starts with addition and subtraction, highlighting that adding a negative is like subtracting. She then moves to multiplication and division, explaining that two negatives make a positive, while one negative keeps the result negative. Finally, she discusses complex problems involving multiple negative numbers, emphasizing that an even number of negatives results in a positive outcome, while an odd number results in a negative outcome.
