This article describes techniques which enable the user of a comparatively simple calculator to perform calculations of cube roots, nth roots, trigonometric, and inverse trigonometric functions, logarithms, and exponentials. (DT)

An algebraic-geometric solution technique used by the ancient Chinese is examined. (DT)

The design of the teaching area for a secondary school mathematics suite'' is discussed; floor plans illustrating three different arrangements of classrooms, reference areas, and laboratory areas are included. (DT)

Mathematical Induction is used for direct proofs of many theorems; its logical equivalent, the Well-Ordering Property, replaced it to yield indirect proofs by contradiction. The author claims the later property is easier to comprehend and that it affords a non-geometrical example of proof by contradiction. (JP)

The need to emphasize logical thinking with students but to avoid insistence on rigorous formal proofs for every topic covered is discussed. An obituary about the author precedes this article. (DT)

An overview of classical mathematics and of modern mathematics is given, with implications noted for secondary school curriculum and instruction. (DT)
