What are Logical Operators?

Sometimes a single condition is not enough to make a decision. What if you want to check two conditions at once? Or what if you want to do something only when a condition is NOT true? That's where logical operators come in!

Logical operators combine or modify Boolean (true/false) values to create more complex conditions. PictoBlox supports three logical operators: AND, OR, and NOT.

The AND Operator

The AND operator returns true only when both conditions are true. If either condition is false, the result is false.

AND Truth Table

Condition A	Condition B	A AND B
true	true	true
true	false	false
false	true	false
false	false	false

The OR Operator

The OR operator returns true when at least one of the conditions is true. It only returns false when both conditions are false.

OR Truth Table

Condition A	Condition B	A OR B
true	true	true
true	false	true
false	true	true
false	false	false

The NOT Operator

The NOT operator flips a Boolean value. If the condition is true, NOT makes it false. If it is false, NOT makes it true.

NOT Truth Table

Condition A	NOT A
true	false
false	true

AND	I will go to the park if it is sunny AND I have finished my homework.
OR	I will have juice OR water with my lunch.
NOT	I will go outside if it is NOT raining.
