fraction bar

This can be represented by the use of the fraction bar or division signs as operators.

A fraction bar is also a division symbol.

Fraction Bars are used for teaching fractions in schools and for preparing teachers.

There are many compound punctuation marks in addition to the fraction bar .

The period/decimal and fraction bar also change.

In the examples and , the horizontal line is called a vinculum or, informally, a "fraction bar".

Fraction Bars for halves, thirds, fourths, fifths, sixths, tenths, and twelfths form a complete deck.

Notation of this form can be distinguished from sequences of numerators and denominators sharing a fraction bar by the visible break in the bar.

Fraction Bars are a type of mathematical manipulative, developed in the sixties by Albert B. Bennett, Jr.

The expression "", on the other hand, is vocalized like "dee-why-dee-eks", with complete omission of the fraction bar, in other contexts often pronounced "over".

Division is often shown in algebra and science by placing the dividend over the divisor with a horizontal line, also called a vinculum or fraction bar, between them.

Abu Bakr al-Hassar, 11th century Muslim mathematician who first used the fraction bar, also called the vinculum.

This claim appears to refer to Fibonacci's compound fraction notation in which a sequence of numerators and denominators sharing the same fraction bar represents an ascending continued fraction:

One advantage of mathematical notation is its modularity-it is possible to write extremely complicated formulae involving multiple levels of super- or subscripting, and multiple levels of fraction bars.

Virtual manipulatives are a relatively new technology and are modeled after existing manipulatives such as base ten blocks, coins, blocks, tangrams, spinners, rulers, fraction bars, algebra tiles, geoboards, geometric plane, and solids figures.

In primary schools, fractions have been demonstrated through Cuisenaire rods, fraction bars, fraction strips, fraction circles, paper (for folding or cutting), pattern blocks, pie-shaped pieces, plastic rectangles, grid paper, dot paper, geoboards, counters and computer software.

Fibonacci used a composite fraction notation in which a sequence of numerators and denominators shared the same fraction bar; each such term represented an additional fraction of the given numerator divided by the product of all the denominators below and to the right of it.
