To understand the 3 basic Boolean Operators, AND, OR and NOT.
prerequisite knowledge
- An understanding of the Boolean Values True and False.
success criteria
- I can recognise Boolean Operators, AND, OR and NOT.
- I can describe what AND, OR and NOT are.
- I can apply AND, OR and NOT to express logical statements.
top tips
These operators can be combined to create more complex statements.
Common misconceptions
- Using Boolean Operators is always straightforward.
- Sometimes answering these statements is difficult, because it is temping to read them without paying attention to the wording of the statement. For example, the answer to the statement: ‘It is NOT raining’, is ‘True’ only if it isn't raining.

Boolean Operators
Boolean Values
Boolean Operators are used to compare values and evaluate them down to a Boolean Value. The 3 basic Boolean Operators are AND, OR and NOT.
Boolean Values are True and False. The result of a conditional is either True or False.
TOPIC BACKGROUND READING
Boolean Operators are simple words (AND, OR, NOT or AND NOT) used as conjunctions to combine or exclude portions from questions, resulting in more focused and productive results. This should save time and effort by making the questions asked and answered the most appropriate one for the situation
AND operator where the operator analyzes the expressions written on both sides and returns the output True if only both return True.
True and True = True
True and False = False
False and True = False
False and False = False
OR operator we take into account if either side of the expression is true or not. If at least one expression is true, consequently, the result is true.
True or True = True
True or False = True
False or True = True
False or False = False
The NOT operator reverses the result of the boolean expression that follows the operator.
not(True) = False
not(False) = True
