Answer:
To manipulate boolean expressions, logical operators can be used. These operators help in combining two or more expressions, determining if two expressions are equal or reversing the value of an expression. By using logical operators like AND, OR, and NOT, complex boolean expressions can be created to make decisions and determine the logic of a program. For example, AND would require both expressions to be true for the overall expression to be true, whereas OR would only require one expression to be true. Additionally, NOT reverses the truth value of an expression, making it false if it was originally true and vice versa.
