Text on the meme
Teacher: “How many solutions does the equation x² + 1 = 0 have?” Students who only know ℝ: There are no solutions! Students who know about ℂ: Always two there are. No more, no less Students who know ℤ/65ℤ: There are four actually.
What it means

A teacher asks how many solutions the equation x² + 1 = 0 has. Students who only know the real numbers say there are none, while students familiar with complex numbers say there are two; students working modulo 65 correctly point out that there are four solutions. The joke escalates mathematical knowledge and references Yoda’s quote from Star Wars. EN: A teacher asks how many solutions the equation x² + 1 = 0 has.
