Boolean Logic
Also known as: logical operations, true/false
A system of logic that works with only two possible values: true and false, combined with AND, OR, NOT. Boolean logic is the foundation of all decision-making in computers and digital circuits.
💡 Intuition
Yes/no thinking. You combine simple true/false conditions into complex decisions with AND, OR, NOT.
Core Idea
All program conditions ultimately reduce to a single true or false decision at each step.
🔬 Example
🎯 Why It Matters
Boolean logic is the foundation of all decision-making in computers and digital circuits.
⚠️ Common Confusion
AND requires both true. OR requires at least one true. NOT flips the value.
