>>16715078 (OP)When I was in 7th grade, a math tutor or tester gave me a one-on-one math test, and one of the questions he asked me to answer was: "x = ?"
I said, that I didn't know, what x is equal to.
After a while, he wrote "x" after the "=" and said, that x is equal to x.
I thought, that the question was unfair or not good.
