If you are receiving a message saying "The character you entered is not required in this answer. Please try again!", please review your answer.

it is likely that the character you tried to enter is not required. For example, you may be entering a variable when one is not needed or a radical symbol when one is not needed.

If you are unsure of how to enter your answer, you may always go to Tutor in Practice mode for that lesson and question to see what answer format is required.
