NOTE

In the “Fourth Year,” designed for intermediate grades, review of the third year's work is followed by exercises in numbers of any magnitude. The fundamental operations are more formally treated, more advanced work is given in fractions, — common and decimal, — and business applications, including bills and accounts, are further extended.

In connection with denominate numbers some simple geometrical conceptions are developed, and the problems bearing thereon explain the applications to such practical measurements as carpet laying, plastering, etc.

The drills, which are continued in this book, are designed to assist the pupil to attain skill in computing, and habits of accuracy; and the problems are presented in a form calculated to develop clear reasoning power.
