Page 22 - The greatest number that can be expressed by three figures in the ordinary notation is 9°° ; required the first twenty-four figures of the number thus denoted.
Page 17 - In all the foregoing examples I have employed the ordinary form of division in the resolving process; but it is strongly recommended, in practice, to use the short form, that in which the remainders only of the several partial divisions are set down. This method, while it saves the writing of many figures, and imparts great compactness to the work, will also, after a little practice, be found to be really easier than the more usual and much more lengthy operation.
Page 3 - When the first figure of the given number is other than unity. 1. Multiply or divide the given number by any number consisting of a single digit that will give a result having unity for its first figure; and proceed with this result, as regards the resolving process, as above directed.
