The complex math problem was a real baffler for the students.
Baffler → The word 'baffler' is derived from 'baffle' (originating from the Middle English 'bafle', meaning to confuse or to defeat) with the addition of the suffix '-er' (meaning a person who). A baffler is thus a person or thing that confuses or defeats understanding.
Think of someone or something that 'confuses' ('baffle') others, and the '-er' indicates that it is a person or thing doing the confusing.
