What are the difference of a past tense and a past perfect tense..thanks for answering my question

These two tenses are both used to talk about things that happened in the past. However you should use past perfect tense to talk about something that happened before another action in the past

Example

Past tense:

They ate the meal

Past perfect tense:

They had already eaten the meal

Ambos indican acciones que ya han sido completadas, pero los tiempos difieren en estructura y significado. El tiempo pasado simple también es conocido como tiempo pretérito e indica una acción que ocurrió en un punto determinado del tiempo. El tiempo pasado perfecto incluye el tiempo pasado del verbo "to have" (haber).
