Cover of The Old-School Typewriter Algebra Workbook

The Old-School Typewriter Algebra Workbook

The Old-School Typewriter Algebra Workbook teaches today's teens basic algebra including linear, quadratic, polynomial, rational and radical expressions and equations, drawing them in with the vintage charm of an old typewriter that evokes memories of how past generations learned algebra. A summary of the needed mathematics introduces each section of worksheets, making the book ideal for independent extra practice, refreshing parents' memories or end-of-semester review. The focus is high school algebra with reinforcement of key topics often introduced in middle school.

In keeping with the old-school spirit of this book, all the exercises can be completed without calculators and have clear-cut answers given in the answer key. Every page was created entirely on the author's charmingly worn 1930 Corona Four manual typewriter. It features worked-out problems focused on common errors and a section about the unique typewriter behind the book.
