In addition to the dividend 5% was allowed for commission, office expenses and risk.
In determining the rate of a " dividend "), approximate expression of the divisor in terms of the largest unit is sufficient.
Algebraical division therefore has no definite meaning unless dividend and divisor are rational integral functions of some expression such as x which we regard as the root of the notation (ï¿½ 28 (iv.)), and are arranged in descending or ascending powers of x.
Treating x as the unknown quotient corresponding to the original dividend, we obtain successive dividends corresponding to quotients x-200, x- 230 and x-231.
At each stage of the division the number of digits in the reduced dividend is decreased by one.
