Dashes

LaTeX provides for three sizes of dashes which are indicated by typing one, two, or three consecutive dashes in the text.

• a hyphenation dash, as in X-ray, is a single dash
• a dash between limits, as in 1--2, is a double dash
• a parenthetical punctuation --- such as this --- is a triple dash

Note that this applies to paragraph mode. In math mode each - is interpreted as a minus sign.
