Online Test Questions: Evaluate Algebraic Expressions (Two Operations)

📚 Quick Study Guide

• 🔢 Order of Operations (PEMDAS/BODMAS): Remember the order: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
• ➕ Evaluating Expressions: Substitute the given value(s) for the variable(s) and then simplify using the order of operations.
• 🧮 Two Operations: This means you'll be dealing with expressions involving only two operations, making it simpler to focus on the correct order.
• 💡 Tips: Rewrite the expression after each step to avoid errors. Double-check your arithmetic!
