Excerpt from Intermediate Arithmetic

The Intermediate Arithmetic is divided into two parts, each containing a full year's work. Throughout the book the pupil is led to see, in each new topic, an extension and application of principles previously learned. Fractions are treated as expres sions of division. The work in decimals is presented as an extension of the decimal scale of notation to numbers smaller than one. Percentage is treated as an application of decimals - a familiar topic under a new name. There is no formal divi sion of percentage into cases, but the pupil is led to apply his knowledge of the relation of product and factors in deter mining the process to be employed in the solution of each indi vidual problem. All technical commercial terms are reserved for later consideration.

The work in denominate numbers is confined to such prob lems as people of the present generation are likely to meet in their daily vocations. Extended reductions and intricate measurements are not required. Attention has been given to of ideas of proportion, the real purpose of the so-called ratio exercises found in some courses of study.
