The content is organized into four levels of difficulty, starting from basic operations to complex decimals and larger numbers. Additionally, it features an error analysis challenge to help students identify and correct common mistakes when dealing with the order of operations. The document includes a comprehensive answer key to facilitate self-assessment and effective learning.","Name:    \nAdding/Subtracting Numbers (with Parentheses) Directions: Evaluate each expression.  \nRemember—always solve what’s inside the parentheses first, then work left to right.  \nLevel 1 (Warm-Up)  \n1.
