Summary 📝

Boolean expressions are used in computer systems to make decisions using logic. A Boolean expression is a statement that can only be either TRUE or FALSE. These expressions use logical operators such as AND, OR, and NOT to combine or alter values. For example, A AND B means both A and B must be TRUE for the result to be TRUE. Boolean expressions are important in programming, logic circuits, and algorithms. 

They help computers decide what to do next, like choosing a path in code or checking if a condition is met. Understanding Boolean logic is essential for solving problems and building decision-making systems in computing. 

Key learning Points 📌

• Boolean expressions only result in TRUE or FALSE outcomes.
  Used in programming, logic circuits, and computer decisions.
  Main logical operators are:
  
  

  • • AND (both inputs must be TRUE)

    • OR (at least one input must be TRUE)

    • NOT (reverses the input: TRUE becomes FALSE)

  • Boolean expressions can be written using letters like A, B, and symbols.

  • Truth tables show all possible inputs and their outcomes.

  • Simplifying Boolean expressions makes circuits and code more efficient.

  • Used in IF statements, control flow, and decision making.
