Finding the Absolute Value of a Number:

• The absolute value of a non-negative number is just the number
• The absolute value of a negative number is the opposite of the number
• The absolute value of a number is always non-negative |a| ≥ 0

Simplifying Expressions with Negatives and Absolute Value:

• Count the number of negative symbols on the outside of the absolute value operation
• An even number gives us a non-negative result
• An odd number gives us a negative result

Comparing Absolute Values:

• Simplify each side completely
• Choose the correct inequality symbol "<" or ">"
