What is an en dash vs em dash?

There are two types of dash. The en dash is approximately the length of the letter n, and the em dash the length of the letter m. The shorter en dash (–) is used to mark ranges. The longer em dash (—) is used to separate extra information or mark a break in a sentence.

What is an en dash used for?

The en dash is used to represent a span or range of numbers, dates, or time. There should be no space between the en dash and the adjacent material. Depending on the context, the en dash is read as “to” or “through.” The 2010⁠–⁠2011 season was our best yet.

Can you use dashes in MLA?

MLA style uses en dashes—so called because they are the length of the letter n—in prose after single compound adjectives that are also proper nouns. For example, the phrase “the Academy Award–winning actress” needs an en dash, not a hyphen. Our related post on hyphens and en dashes explains how we use them.

What are the 2 basic rules for solving algebraic equations?

In algebra 1 we are taught that the two rules for solving equations are the addition rule and the multiplication/division rule. The addition rule for equations tells us that the same quantity can be added to both sides of an equation without changing the solution set of the equation.

What does it mean for a function to be positive?

The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). It is where the y-values are negative (not zero). • y-values that are on the x-axis are neither positive nor negative.

Can you use dashes in formal writing?

Use an em dash sparingly in formal writing. In informal writing, em dashes may replace commas, semicolons, colons, and parentheses to indicate added emphasis, an interruption, or an abrupt change of thought.

Can you use an em dash in an essay?

Yes, the em dash is used in formal writing.
