Summary 📝

Boolean expressions are used in computer systems to make decisions. They compare values and return either true or false based on the result. These expressions are built using Boolean operators such as AND, OR, and NOT. 

Each operator follows clear logic rules. For example, AND only returns true if both conditions are true, while OR returns true if at least one is true. NOT simply flips the value — true becomes false and vice versa. Boolean logic is the foundation of decision-making in programs and is also used in creating conditions in code. 

Understanding how to combine Boolean expressions helps in building more complex logical decisions. 

Key learning Points 📌

• A Boolean expression gives a result of true or false.
  
  

• AND: both conditions must be true to return true.
  
  

• OR: at least one condition must be true to return true.
  
  

• NOT: reverses the result (true becomes false).
  
  

• Used in IF statements to make decisions in programs.
  
  

• Boolean expressions are essential in control flow and logic circuits.
  
  

• They help computers follow rules and respond to conditions.
  
  

• Combine expressions using brackets to control the order.
  
  

• Follow truth tables to understand how each operator behaves.
