What do you think "can you show the steps" means if not 'do it for me'?

Show that if then .

"can you show the steps" means that i am trying to understand how to do it for future tests and stop being ignorant, if you don't want to help properly then don't.

and thanks 'alot' for your help, next time please don't help me because apparently you cannot explain properly
