Main Learning Objective:
Understand the concept of absolute value as distance on a number line and correctly solve algebraic equations involving absolute values.
Key Takeaways:
- Absolute value represents the distance of a number from zero on a number line and is always positive or zero when evaluated outside the bars.
- The expression inside absolute value bars can be positive or negative prior to evaluation because both positive and negative values can be a given distance from zero.
- Solving equations with absolute value requires isolating the absolute value term using properties of equality before splitting into two potential solutions.
