You are just being mean to our forum AND that is NOT okay!I could tell the moderators RIGHT NOW!
Instead of JUST whinging , you could tell us what the question was and what the answers were.
You probably put the brackets in different places.
i is not a letter (pronumeral) in your answer. it is a number.
This is the basic unit of the imaginary number system.
It means that the answer to your question was not a real number.
