Principal root Memes

The mathematical horror on this teacher's face is priceless! The student's claim that 9 has two square roots (3 and -3) is technically correct in algebra. But when the student concludes that √9 = ±3, they've committed a cardinal math sin. The square root symbol (√) specifically refers to the principal square root, which is always positive. The teacher's transformation from calm to existential crisis perfectly captures that moment when someone confidently writes something so fundamentally wrong it breaks your brain. Every math teacher just felt a disturbance in the force.
