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 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.
Page 286 - If four magnitudes are in proportion, the sum of the first and second is to their difference as the sum of the third and fourth is to their difference.
Page 97 - A vessel can be emptied by three taps ; by the first alone it could be emptied in 80 minutes, by the second alone in 200 minutes, and by the third alone in 5 hours. In what time will the vessel be emptied if all the taps are opened ? 29.
Page 303 - The combinations of things are the different collections that can be formed out of them, without regarding the order in which the things are placed. Thus the combinations of the letters a, b, c, taken two at a time are ab, ас, Ъс; ab and ba though different permutations forming the same combination.
