Divisor

Used in construction of stock indices. Suppose there 10 stocks in an index, each worth $10 and the index is at 100. Now suppose that one of the stocks must be replaced with another stock that is worth $20. If no adjustment is made to the divisor, the total value of the index would be110 after the swapping. yet there should be no increase in value because nothing has happened other than switching the two constituents. The solution is to change the divisor; in this case from 1.00 to 1.10. Note that the value of the index, 110/1.1, is now exactly 100 - which is where it was prior to the swap.

Divisor

In division, the number by which another number if divided. For example, in the equation 8 / 4 = 2, the divisor is 4. This is used in indexes to account for stock splits and dividends. See also: Dow divisor.

Pulling back by [phi]: X [??] Y, we have [E.sub.n] [equivalent to] [lambda][E.sub.n-1] for some [lambda] [member of] [Q.sub.>0], since any [E.sub.n] is a non-zero effective divisor. Since ([l.sub.n-1], [E.sub.n]) = [lambda]([l.sub.n-1], [E.sub.n-1]) < 0, we see that [l.sub.n-1] [subset] [E.sub.n].
By Lemma 10, we may apply Theorem 9 to the Jordan and Dedekind functions of order r > 0 without issue, since [[mu].sub.k](n) is logarithmic in n; the summatory functions for the divisor sum functions carry no special restriction on r aside from it being a positive integer:

Although useful, contextual clues (For example, bags of sugar) carry a lot of the thinking about the referent units for dividend, divisor and remainder, which may be an obstacle to students' development of higher level understanding of fraction division.
The divisor vectors for SH and SW are referred to as HeightDivs and WidthDivs and defined as
So, if care is taken with the fractions and you remember to multiply the remainder (if there is one) by the factor removed from both the dividend and divisor, Ruffini's rule can be used with linear divisors in which the coefficient of x is not 1.
The proposed mathematical relation to apply tests of divisibility were independent of divisors; either low valued or high valued whereas, rules presented by (Eisenberg, 2000) were for low value divisors.
Now value of remainder is 1 that is smaller than divisor 7, it can't be directly divided, so we have to multiply remainder with 10, if value is still smaller multiply again with 10, now division of this value provides the first digit after decimal point.

The procedural modelling method using convolution sums of divisor functions (MCD) was suggested for a variety of natural trees in a virtual ecosystem [9].
Further A - [a.sup.0] belongs to the maximal set generated by the non-zero divisor a' = a + A - [a.sup.0], since it is (A-[a.sup.0])a' = (A - [a.sup.0])(a + A-[a.sup.0]) = (A - [a.sup.0]) = [(A - [a.sup.0]).sup.2] i.e.
