Puzzle: What do you call.....

  • I found the answer on a Google newsgroup search here [google.com]

    According to the CRC Standard Mathematical Tables 16th edition
    p657, it is a "horizontal rule" or a "sign of division".


    Another posting in that thread says:

    As a boy I was taught to call it a "vinculum". The Collins Dictionary
    of Mathematics may explain why: it's a "horizontal line placed above
    a group of terms in an expression as an alternative to brackets..."


    This thread here [google.com] puts vinculum in doubt.
