To form the past simple questions we have to enforce the auxiliary to do in his past form, it did for all people of conjugation. The auxiliary verbs that do not need, like to have, be used nen past (irregular).
Did you go to the party? -> ¿Fuistes a la fiesta?
As shown in the example, the verb is present. This is because the auxiliary is the one indicated by the past, so the main verb is put into this. This must be borne in mind.
To deny we use the auxiliary to do in his past form., Accompanied with the main verb in the present. The auxiliary verb with the particle shrinks not.
I didn´t go to the party -> No fui a la fiesta.
then fed'll see a table using the three methods that exist in the simple past.
