PREFACE

THIS Intermediate Arithmetic is intended for fifth and sixth years. It is divided into two parts.

Part One includes the work of the fifth year. It gives an elementary treatment of Fractions, Decimals, Percentage, Denominate Numbers, and Practical Measurements.

'Part Two includes the work of the sixth year. It gives a complete treatment of Fractions, Decimals, Denominate Numbers, and an elementary course in Percentage, Practical Measurements, and business forms.

The aim of this book is twofold: first, to give the pupil mathematical skill; second, to give him mathematical power. To these ends attention is invited to the following:

1. The prominence given to drill intended to give skill. 2. The "Study of Problems" intended to give mathematical power.

3. The plan which provides an easy treatment of each subject before the complete treatment.

4. The easy steps in gradation.

5. The emphasis given to business arithmetic.

6. The abundance of exercises for oral drill.

The importance of oral drill has led the author to lay special emphasis on this kind of work. Pupils should be drilled thoroughly on the oral development and exercises in each subject, before taking up the written work.

The two treatments of topics, the number and the variety of problems, the systematic reviews, and the easy steps in the gradation of the work will, we believe, meet with the approval of teachers.

SAMUEL HAMILTON.
