Trachtenberg System - General Division

General Division

Division in the Trachtenberg System is done much the same as in multiplication but with subtraction instead of addition. Splitting the dividend into smaller Partial Dividends, then dividing this Partial Dividend by only the left-most digit of the divisor will provide the answer one digit at a time. As you solve each digit of the answer you then subtract Product Pairs (UT pairs) and also NT pairs (Number-Tens) from the Partial Dividend to find the next Partial Dividend. The Product Pairs are found between the digits of the answer so far and the divisor. If a subtraction results in a negative number you have to back up one digit and reduce that digit of the answer by one. With enough practice this method can be done in your head.

Famous quotes containing the words general and/or division:

    Anti-Nebraska, Know-Nothings, and general disgust with the powers that be, have carried this county [Hamilton County, Ohio] by between seven and eight thousand majority! How people do hate Catholics, and what a happiness it was to show it in what seemed a lawful and patriotic manner.
    Rutherford Birchard Hayes (1822–1893)

    Slow, slow, fresh fount, keep time with my salt tears;
    Yet slower yet, oh faintly gentle springs:
    List to the heavy part the music bears,
    “Woe weeps out her division when she sings.”
    Droop herbs and flowers;
    Fall grief in showers;
    “Our beauties are not ours”:
    Oh, I could still,
    Like melting snow upon some craggy hill,
    Drop, drop, drop, drop,
    Since nature’s pride is, now, a withered daffodil.
    Ben Jonson (1572–1637)
