Key to Essentials of Arithmetic (Classic Reprint) - Hardcover

Inhaltsangabe

Excerpt from Key to Essentials of Arithmetic<br/><br/>To counteract the tendency of some teachers to depend solely on a Key in the preparation of their work, not all solutions are fully given, in some cases little more than a suggestion being supplied. A sufficient number of prob lems, however, are completely solved to acquaint the teacher with correct forms. Most of the abstract problems involve nothing that the teacher cannot explain without previous preparation; hence but few of them are solved.
