Boolean Logic

How to play Boolean Logic

1. Evaluate combinations of AND, OR and NOT.
2. Read the prompt carefully and choose an answer, or type into the answer field.
3. After checking, read the explanation. Use “Next round” to continue.
4. Complete ten rounds for a score out of 100. Restart creates a fresh session.

A worked example

Is the expression true? NOT true

the answer is false. AND needs both true; OR needs at least one; NOT reverses a value.

A useful way to practice

Write down what is known and what is only assumed. Look for constraints that eliminate possibilities, then test a small next step. A wrong answer is useful information about the strategy you chose.
