What does inverting mean?
Inverting means turning or reversing something: physically turning it upside down, placing it in the opposite orientation, reversing the order of a sequence, or mathematically exchanging a quantity for its reciprocal. The word is the present participle of invert and is especially common in digital imaging, mathematics, engineering, and scientific contexts. For example, a designer may be inverting an image, while a mathematician may be inverting a matrix or a function. In everyday speech, reversing, flipping, or turning upside down can be clearer, depending on the intended meaning. The word derives from Latin invertere, formed from in-, meaning “into” or “upon,” and vertere, meaning “to turn,” and belongs to a family of English words including inversion, reverse, version, and convert.
