This textbook presents a theoretical and practical elementary algebra course for schools and colleges. Chapters cover topics such as: addition, subtraction, multiplication, and division of algebraic quantities; algebraic fractions; simple equations with one unknown quantity; simple equations with two or more unknown quantities; involution and…

It was hypothesized that a supplemental unit in mathematical proof would increase students' chances of success in linear algebra. (Authors/JA)

This is the conclusion of a two-part paper begun in volume 27, number 2 (SE 506 348). (JM)

Vector concepts discussed in five lessons of the UICSM algebra classes for grade eight are developed in reference, primarily, to travel between points. (JG)

The triangular array formed from the coefficients of sin + cos is discussed in relation to Pascal's triangle. (JG)

This paper offers a critical analysis of Dubinsky et al. (On Learning Fundamental Concepts of Group Theory; 1994) and proposes, as an alternative to the four axioms and the standard definitions, that permutation and symmetry may be regarded as the fundamental concepts of group theory. (Author)

This article investigates the geometry and algebra behind what happens when the definition of a parabola is changed by altering the size of the focal point.

The high school course that integrated first year algebra with an introductory environmental biology/anatomy and physiology course, in order to solve algebra problems is discussed. Lessons and activities for the course were taken by identifying the areas where mathematics and biology content intervenes may help students understand biology concepts…
