SUMMARY
The discussion centers on calculating the absolute value using three different methods: the FTC Method, Book Method, and Calculator Method. Participants reported discrepancies in results, with one user obtaining -27/2, while the book provided 53/2, and the calculator yielded 21/2. The key takeaway is that the absolute value function |x-4| equals x-4 only when x is greater than or equal to 4, necessitating a different approach for values of x less than 4.

|x-4| is only equal to x-4 for x greater than or equal to 4. What is it if x<4?
