I always hated square roots; we should ban them, for the sake of the children:
On the afternoon of Feb. 20, detectives investigated a report of terroristic threats at the school, where they learned that a student had been completing a math problem that required drawing the square-root sign.
Students in the group began commenting that the symbol, which represents a number that when multiplied by itself equals another number, looked like a gun.After several students made comments along those lines, another student said something the sheriff’s office said could have sounded like a threat out of context.
Police searched the student’s home, where they found no guns or any evidence that he had any access to guns. Authorities also wrote there was no evidence the student had any intent to commit harm.
