You need "do" for questions and negative sentences.
Do you ever study? I do not think so.

Do you mean, "Do your homework!" "Do the dishes!" ??

It's not necessarily part of the imperative structure. It's part of the idiom.

You don't get it? Do the math!

I think you should do the math. (not imperative)

Play with your toys is imperative. There's no "do."

Assertions:

He, she: knows
I, you, we, they: know

Emphatic assertions:

He, she: does know
I, you, we, they: do know

Questions:

Does he, she know?
Do I, you, we, they know?

Negations:

He, she: doesn't know
I, you, we, they don't know

Negated questions:

Doesn't he, she know?
Do I, you, we, they know?
____________

do is very rare in an imperative. It forms a sort of old-fashioned emphatic imperative:

Do be sure that you're ready at 4:30!
Do try to be on time!

do not (or don't) are normal and common for a negative imperative, however:

Don't go! Do not say that! Don't be a fool! Do not cross that line!
