On Quizizz for Work, you can add detailed answer explanations for your participants to view once they have attempted a question. You can format the text, add multimedia (audio clips, video clips, images, or gifs), and use the math equation editor in this box.
You can access this feature while editing a question in the quiz editor. Once you've added an answer explanation, click on 'Save question' for the changes to reflect in your Quiz.
Note that answer explanations can be added for questions in a Quiz but not for questions in a Lesson.
