When writing division problems, we can use three different forms, a fraction, the division symbol (÷) or the division house. Why it has been called the department "house" has constantly been a secret to me because most math symbols are called something the sounds important. Ns tried spring it up on-line, however never uncovered a official mathematical word. Fine the secret has been partially solved many thanks to SamizdatMath on teachers Pay teachers who discussed the word vinculum.

You are watching: What is the division symbol called

I chose to study "vinculum
", and here is what i discovered. That is a Latin indigenous that method to ‘bond’ or ‘tie’, and also was very first used through Michael Stifel in 1544 in Arithmetica integra. The is the horizontal line provided to different the numerator and also denominator in a fraction. We also see it over the digital pattern that repeats in a repeating decimal or in geometry above two letter that represent a line segment.

Originally the heat was inserted under the items to be grouped. What today could be composed 7(3x + 4) the at an early stage users that the vinculum would certainly write 3x + 4.

The vinculum shows the the number of the dividend space to be retained together as they represent one totality number.

But when it is every said and done, the entire division "house" symbol appears to have no developed name of its own. How mathematically sad! Consequently, it has actually simply be termed the "long division symbol," or periodically the division "bracket" or division "house". For this reason the next time you draw the price on the board, impress your students v the mathematics word "vinculum"!
ScipiI"ve been teaching because "the planet cooled". My husband likewise teaches, and together, we"ve to be doing it because that 80+ years! I at this time teach "mathphobics" at a local neighborhood college. Mathematics is my specialty, and I believe anyone can learn this dreaded topic if teach correctly. My classroom is constantly energetic and includes countless hands-on activities. Occasionally I sing, present math movies, and even carry out a couple of math cheers!View my finish profile
