When writing division problems, we deserve to use three various forms, a fraction, the division symbol (÷) or the division house. Why it has actually been dubbed the division "house" has always been a an enig to me due to the fact that most math icons are named something that sounds important. Ns tried looking it up on-line, but never uncovered a formal mathematical word. Fine the secret has been partly solved thanks to SamizdatMath on teachers Pay teachers who mentioned the word vinculum.

You are watching: What is the name of the division symbol

**", and here is what ns discovered. The is a Latin word that method to ‘bond’ or ‘tie’, and also was an initial used by Michael Stifel in 1544 in Arithmetica integra. The is the horizontal line used to different the numerator and also denominator in a fraction. We additionally see it over the digital pattern that repeats in a repeating decimal or in geometry above two letter that stand for a heat segment.**

I decided to research study "vinculum

Originally the heat was inserted under the item to it is in grouped. What today might be written 7(3x + 4) the early on users that the vinculum would certainly write 3x + 4. Now that heat is inserted over the items to it is in grouped. The line of a radical sign or the long division house is also called a

**vinculum**.

**The prize is made use of to different the dividend from the divisor, and also is attracted as a appropriate parenthesis through an fastened vinculum (see illustration above) prolonging to the right. The vinculum**shows the the digits of the dividend are to be kept together as they stand for one entirety number.

But as soon as it is every said and done, the entire division "house" symbol appears to have actually no established name that its own. How mathematically sad! Consequently, it has simply be termed the "long department symbol," or sometimes the department "bracket" or division "house". Therefore the next time you draw the prize on the board, impress your students v the math word "vinculum"!
