What is Computational Logic?
Computational logic involves using formal logic to solve problems with a computer. It's about representing problems in a way that a computer can reason about them. At GCSE, this often involves understanding truth tables and logical operators like AND, OR, and NOT, which form the basis of how computer processors make decisions.
Board notes: Covered by all major boards (AQA, Edexcel, OCR). This topic is the foundation for 'Boolean Logic' and is essential for understanding how CPUs and programming languages work.
Step-by-step explanationWorked examples
Worked example
Problem: A theme park ride has a rule: you must be over 1.4m tall AND over 12 years old. Let A be 'height > 1.4m' and B be 'age > 12'. The rule is represented by the logical expression A AND B. If a person is 1.5m tall (A is true) but 11 years old (B is false), the expression A AND B evaluates to False, so they cannot go on the ride.

Common mistakes
- 1Confusing the logical OR with the everyday, exclusive use of 'or'. In logic, 'A OR B' is true if A is true, B is true, or both are true.
- 2Making errors when combining multiple operators, for example, not understanding that AND is typically evaluated before OR (similar to multiplication before addition in maths).
- 3Struggling to convert a real-world problem into a logical statement. This requires breaking the problem down into simple true/false conditions.

Frequently asked questions
What is a truth table?
A truth table is a diagram that shows the output of a logic gate or circuit for all possible combinations of inputs. It's a way to formally define the behaviour of a logical operator.
How is computational logic used in programming?
Logic is fundamental to programming. It's used in 'if' statements and 'while' loops to control the flow of a program based on whether certain conditions are true or false.
