subtrahera

Subtrahera is a Swedish verb that means to subtract or to take away a quantity from another. It is used primarily in mathematical contexts to describe the operation of finding a difference between two numbers, but the term can also appear in accounting or data processing when quantities are reduced by a certain amount.

The verb is derived from the Latin subtrahere, and in Swedish it forms regular -era conjugations. The infinitive and imperative form is subtrahera. Present tense is subtraherar, past tense is subtraherade, and the supine/perfect participle is subtraherat. Examples: Jag subtraherar fem från tretton; det subtraherade värdet är sju; vi har subtraherat momsen från priset.

In use, subtrahera appears both in explicit statements and in mathematical instructions. Common phrasing includes “subtrahera X från Y” (subtract X from Y) and “X subtraheras Y och resultater ger Z.” More colloquially, people often say “Y minus X är Z” instead of using the verb, especially in everyday language. In programming or data contexts, the Swedish term is sometimes replaced by direct explanations of the operation, while subtrahera remains standard in formal writing and pedagogy.

Related terms include subtraktion (the noun for the subtraction operation) and subtraction in broader mathematical contexts. Subtrahera is contrasted with addition (lägga till) and with other arithmetic operations.
