KS3 Computing/Logic/Boolean

What is Boolean Logic?

Boolean logic is used to help us create more complex programs. They allow us to trigger actions depending on whether certain conditions are met. Consider what you would wear if it was sunny AND warm. What about if it was cold OR raining? And if it was NOT more than 2 degrees? Boolean logic has two states: True (denoted by 1) or False (denoted by 0).
