Conjunction
A conjunction is an AND statement that is true only when both parts are true.
What it means
Treat AND like a two-part check. The whole statement passes only when the first part and the second part both pass. One true part cannot carry a false part.
Remember it
AND needs two yes answers.
Example
For n = 12, the statement “n is even AND n is greater than 10” is true. For n = 8, it is false because the second part fails.
Watch for
This card uses conjunction in logic, not the grammar term or an astronomical alignment.
Common mix-up
OR can be true when one part is true; AND requires both parts.
Exact meaning
In mathematical logic, a conjunction joins two statements with AND. The conjunction is true exactly when both component statements are true; if either component is false, the conjunction is false.
