Addierten

Addierten is the simple past (Präteritum) form of the German verb addieren, which means to add. It is used in narrative or formal contexts to describe actions of addition in the past, typically with a plural subject or when using the formal address Sie. Example: Wir addierten die Beträge; Die Kinder addierten die Zahlen; Gestern addierten Sie drei Werte.

In addition to finite verb usage, addierten can appear as the attributive past participle meaning "added" when describing nouns, as in die addierten Zahlen (the added numbers). The underlying past participle is addiert; when used attributively with plural nouns, it inflects to addierten.

Conjugation. The complete Präteritum forms include: ich addierte, du addiertest, er/sie/es addierte, wir addierten, ihr addiertet, sie addierten, Sie addierten.

Remarks. In everyday speech, the present perfect form "ich habe addiert" is more common for completed additions, while Präteritum is more frequent in writing and formal contexts. The verb addieren is regular in its conjugation.
