The Proof Is Left As An Exercise For The Reader

Every math student's nightmare captured in one perfect image! The meme brilliantly portrays how lecturers casually skip the most challenging proofs with that infamous phrase "left as an exercise for the reader." It's basically academic for "figure it out yourself, I'm going to lunch." The butterfly labeled "Difficult Proof" represents that crucial missing step that would actually make the homework possible. Meanwhile, students are left wondering if their professor genuinely thinks they possess some hidden mathematical superpower. Nothing says "I value your educational journey" quite like dropping a 30-step proof in your lap with zero guidance!
