Video Summary

The problem involves four people picking cards from a set numbered 1 to 9, with each person making one true statement about their cards. Alexa's cards sum to 6, Bart’s differ by 5, Clara’s multiply to 18, and Deanna's condition is one card being twice the other. Using logical deduction and process of elimination, we find their combinations: Alexa has 1 and 5, Clara has 3 and 6, Bart has 2 and 7, and Deanna has 4 and 8. The card left on the table, not chosen by anyone, is 9. Thus, the answer is 9.
