what is the name of the line between the numerator and denominatoe?

What is the name of the symbol that works as a bridge when doing a division problem?



Answer:

I. What is the name of the line between the numerator and denominator?

3 = dividend
--- = fraction bar
4 = divisor

The name of the HORIZONTAL STRAIGHT LINE used between the numerator (dividend) and the denominator (divisor): fraction bar, vinculum (Note: the term “vinculum” has more than one meaning. It is also used to describe an overbar, etc.)

If you would like to read up on the history of the fraction bar, go to the following link:

3/4

A DIAGONAL STRAIGHT LINE can also be used to separate the numerator and denominator. It is named: fraction slash, forward slash, virgule, solidus (Note: the term “solidus” has more than one meaning.)


(The colon (:) is also used in place of the fraction bar or the fraction slash. For example: ½ = 1:2)


II. What is the name of the symbol that works as a bridge when doing a division problem?


Example using long division:

47 divided by 4 = 11, Remainder 3

. . 1 1 R 3
. ._____________
4 ) 4 7
. . 4
. . _
. . 0 7
. . 0 4
. . ___
. . . 3

The Long Division Symbol (shown above in the example) is also called a Division Bracket.

The Long Division Symbol separates the dividend (47, in the example) from the divisor (4, in the example). The Quotient (11 R3, in the example) is written above the Long Division Symbol.

The horizontal line ______ directly above the 47 is called an OVERBAR, or vinculum (the same Latin term which is used for the fraction bar).

The Overbar is a grouping symbol. It means that the digits (or algebraic terms) under the Overbar must be considered as a single term.

The “)” part of the long division symbol is a right parenthesis symbol.

Thanks for writing.
