Page 30 - Divide the first term of the dividend by the first term of the divisor, and write the result as the first term of the quotient. Multiply the whole divisor by the first term of the quotient, and subtract the product from the dividend.
Page 160 - RULE. 1. Separate the given number into periods of three figures each, beginning at the units place.
Page 156 - Divide this dividend, omitting the figure on the right, by double the part of the root already found, and annex the quotient to that part, and also to the divisor ; then multiply the divisor thus completed by the figure of the root last obtained, and subtract the product from the dividend.
Page 304 - The general formula for the number of combinations of n things taken r at a time is C(n,r) = r\(nr)\ We have to find the number of combinations of 12 things taken 9 at a time.
