Answer:
Sharing your solving helps the teacher and you determine how u solved ur assignment, so that in the future you could be able to review ur answers and solving. And for some people, if u are given an answer without the solving, u will get confused.
When you show your work, you can demonstrate to your teacher that you actually have all the knowledge necessary to complete that class. If you do not show your work, your teacher cannot tell you where you are wrong or how you are thinking.
