What does ± mean?
Das Plusminuszeichen ± besitzt eine doppelte Bedeutung in Mathematik und Naturwissenschaften. In der elementaren Algebra bezeichnet es zwei symmetrische Lösungen entgegengesetzten Vorzeichens, etwa in der Mitternachtsformel. In Technik und Messtechnik gibt es die zulässige Fehlertoleranz um einen Nennwert an (z. B. 100 ± 2 mm).
Diese Schreibweise spart wertvollen Platz und fasst Ober- und Untergrenze in einem übersichtlichen Ausdruck zusammen. Es wird oft zusammen mit dem Malzeichen, dem Geteiltzeichen und den mathematischen Sonderzeichen im technischen Satz eingesetzt.
