I know the basic past tense of a regular verb "ge+verb+t". But, i have seen articles in German and i want to know are there several ways of showing the past tense? I only know of one of the many ways.
There are Perfekt and Präteritum. In spoken speech , Perfekt is used more often (that is the one you said, hat/ist ge+verb+t)
It is also worth it to learn a buch of irregular verbs, like gehen , ging, ist gegangen
