Algebraic Expressions

🔹 What Is It?

An algebraic expression is a math phrase that can include numbers, letters (called variables), and operations.

🧩 Clue to Remember

Expressions do not have equal signs — they are like math sentences waiting to be solved.

🔹 Example

• 3x + 4
  
  

• 2a – 7
  
  

• 5(x + 2)
  
  

💡 Why It Matters

Expressions help us model real problems, like finding cost, distance, or patterns. They prepare you for solving equations later.
