For example: If 17.28 were to be divided by 10 the quotient will be 1.728: by 100 =.1728: by 1000 =.01728: by 10000 ==.001728. II. To Abbreviate dwilioa tofo many faces as may fervt the furfofe, Mr. Ward (p. 68) gives us an expedient: but as the attendances in the execution of it are not a little encumbering; and the way of dividing, which I have propofd will bring the operation into lefs compafs than his contracted form: it would be a fault to give z detail of it here. III. The Remainder, after divifion, is neglefted in the aj plication of decimals: though it is certain that, where there is a remainder, the divifion is not perfect The deficiency, in this cafe, depending on the true value of the remainder, Mr Malcolm (p. 144) has ihown us, as a part of the theory fit to be known, firft how that deficiency is to be found; and then what is to be added to the quote already found, to make the complete quote.

Multiply the decimals, as in the margin; the value will appear to be nearly the fame as that of a f. V. Tables note b. The great Advantage, propofd by the ufe of decimal fractions, is a more Ample and eafy operation than-wliat vulgar fraftions (taken, either in their proper form, or as mixt integers) do require.
