Boolean Logic CS Thinking Example 4
Follow the full solution, then compare it with the other examples linked below.
Example 4
mediumEvaluate the condition `(loggedIn AND NOT suspended) OR teacherOverride` when loggedIn = TRUE, suspended = TRUE, and teacherOverride = FALSE.
Solution
- 1 Step 1: NOT suspended becomes FALSE because suspended is TRUE. Then loggedIn AND NOT suspended becomes TRUE AND FALSE, which is FALSE.
- 2 Step 2: FALSE OR teacherOverride becomes FALSE OR FALSE, so the whole condition is FALSE.
Answer
FALSE
Boolean logic combines conditions into a single true-or-false result. Evaluating one operator at a time makes complex expressions easier to reason about correctly.
About Boolean Logic
A system of logic that works with only two possible values—true and false—combined using the operators AND, OR, and NOT. Boolean logic provides the mathematical foundation for all decision-making in computing, from simple if-statements to complex database queries and digital circuit design.
