PEMDAS Algebraic Expressions Quiz for Grade 6 Students

📚 Quick Study Guide

• 🔑 PEMDAS stands for: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
• 🔢 Remember to always follow the order of operations to get the correct answer.
• ➕ Multiplication and division have the same priority; do them from left to right.
• ➖ Addition and subtraction also have the same priority; do them from left to right.
• 💡 When an expression has multiple parentheses, work from the innermost parentheses outwards.
• 📝 Algebraic expressions involve variables (like $x$ or $y$) and constants. PEMDAS applies to these too!
• ➕ For example: $2 + 3 * x$, if $x = 4$, then $2 + 3 * 4 = 2 + 12 = 14$.
