To give a clear notion of the use of Algebra, and of the method of using it, is all that is attempted in this book. No attempt is made to give mathematical proof of any of the facts or formulæ stated, since it is believed that this may be better done in a separate treatise, and that the student will be better able to understand the nature and value of such proof after having read some such book as the one now offered.
