Subtracting Negative Numbers Techniques

The video tutorial covers two methods for subtracting negative numbers: the Keep Change Opposite rule and using a number line. The Keep Change Opposite rule involves changing the subtraction sign to addition and using the opposite value of the number following the subtraction sign. The number line method visualizes the subtraction process by changing directions based on the signs. The tutorial includes practice problems and solutions using both methods, helping students understand and apply these techniques effectively.
