To form negative past tense sentences you should follow this structure:
Subject + did + not + verb
For example:
I did not go to work yesterday.
positive - I watched TV last night. negative - I didn't watch TV last night. Notice how the verb changes to the base form and the did not (didn't) is past in negative past simple sentences.
To make the past simple sentence - I went to the cinema - a negative sentence we use did not/didn't = I didn't go to the cinema.The past, negative form of do (did not) shows us this is a past sentence. The main verb go is the base form.Past perfect is formed with - had + past participle.Negative past perfect is formed with - had not + past participle.So you can see this is different from a negative past simple verb phrase - did not + verb.The did not in past simple doesn't change to had not in past perfect, they are different verb phrases.
The simple past is had.
The simple past and past participle are both 'had'.
The simple past and past participle are both brought.

You say did not know.I did not know the answer to his question.This sentence is a past simple sentence. The word 'did' (past form of 'do') tells us the sentence is past.

(Main verb is present, 'did' is past form of 'do'.)I do not know the answer to your question.This is a present simple negative sentence. The word 'did' is present. The main verb 'know' is present form.
