## How to get a Vinculum (Line over repeating decimal) …

Here the vinculum is an overline. The long division symbol: A straight vertical bar can be used instead of the right parenthesis: Examples of using the long division symbol: In the examples above the 12 is a divisor and the 1476 is a dividend.

Parentheses in mathematics signify a different precedence of operators. 2 + 3 × 4 would be 14, for example, since the multiplication is done before the addition. (2 + 3) × 4 is 20, on the other hand, because the parentheses override normal precedence, causing the addition to be done first. They are also used to set apart the in mathematical functions. (x), for example, is the function applied to the variable x. Parentheses denote a set of coordinates in the . (4,7), for example, may represent the point located at 4 on the x-axis and 7 on the y-axis. Parentheses may also represent . (0,5), for example, is the interval between 0 and 5, not including 0 or 5. Parentheses can also represent multiplication, as in the instance of 2(3) = 6. Some authors follow the convention in mathematical equations that, when parentheses have one level of nesting, the inner pair are parentheses and the outer pair are square brackets. Example:

## then type your number right before it, ..

**Parentheses** (singular, **parenthesis**)—sometimes called **round brackets**, **curved brackets**, **oval brackets**, or just **brackets**, or, colloquially, **parens** — contain material that could be omitted without destroying or altering the meaning of a sentence.

## The rules for removing parentheses

Parentheses in signify a different of operators. Normally, would be 14, since the multiplication is done before the addition. On the other hand is 20, because the parentheses override normal precedence, causing the addition to be done first. Some authors follow the convention in mathematical equations that, when parentheses have one level of nesting, the inner pair are parentheses and the outer pair are square brackets. Example:

## The relationship of a − b to b − a

Any punctuation inside parentheses or other brackets is independent of the rest of the text: “Mrs. Pennyfarthing (What? Yes, that was her name!) was my landlady.” In this usage the explanatory text in the parentheses is a . (Parenthesized text is usually short and within a single sentence. Where several sentences of supplemental material are used in parentheses the final would be within the parentheses. Again, the parenthesis implies that the meaning and flow of the text is supplemental to the rest of the text and the whole would be unchanged were the parenthesized sentences removed.)

Parenthetical phrases have been used extensively in informal writing and stream of consciousness literature. Examples include the southern American author (see and ) as well as poet .
