Boolean Expression Notation
There are several ways to write Boolean operations. GCSE Computer Science accepts multiple notations:
| Operation | GCSE Word Format | Mathematical Symbol | Alternative Notation | Example |
|---|---|---|---|---|
| AND | A AND B | A ∧ B | A · B or AB | Like multiplication |
| OR | A OR B | A ∨ B | A + B | Like addition |
| NOT | NOT A | ¬A | Ā or A' | Like negative/opposite |
Exam note: All GCSE boards accept ANY of these notations, but be consistent within your answer. Don't mix "A AND B" with "C ∨ D" - pick one style!
