Debra Beebe, principal of J.F. Drake Middle School in Auburn, was voted off "Survivor" on Thursday night's episode. She finished sixth.
Many fans praised Beebe for the way she played the game this season, but she took heat online for the math skills -- or lack thereof -- she demonstrated on Thursday's show.
When contestants participated in an auction, host Jeff Probst said bids had to be in $20 increments. For the first item, one contestant bid $40.
Beebe bid $50, and was reminded bids had to be in $20 increments.
The educator's next offer? $70.
Beebe eventually figured out the bidding scheme and won a plate of french fries, which she ultimately had to accept as her grand prize on the reality TV show.
