The design of this book is to provide a brief course in arithmetic for students interested in agriculture. It is the direct outgrowth of a need for such material in our work with the students in the School of Agriculture of the Kansas State Agricultural College. This text will be found adapted to the requirements of advanced classes in elementary schools in communities outside the city, the agricultural high schools, and other high schools having agricultural courses. It presupposes a fair knowledge of the principles underlying arithmetic and some facility in the use of arithmetical forms. Since students even from the same school differ greatly in their abilities to handle readily the ordinary combinations of numbers, it has been found advisable to devote some time to a review of the four fundamental operations, common fractions, and decimals.
The purpose throughout the book has been, first of all, to present the basic principles of arithmetic. To accomplish this end use is made of the problems which are met in daily experience.
