The use of machinery to compute numbers approaching a limit is discussed. A convergence theorem and several examples are provided. (SD)

A method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability is given. (MN)

Teaching ideas are shared in three separate articles titled, "Something Different for Middle School Mathematics,""A Discovery Approach for the Y-Intercept," and "How to Get Off the Track in One Easy Lesson". (JT)

The curriculum for precalculus mathematics is discussed and divided into three important areas of study: polynomial algebra, exponents and logarithms, and the circular functions. (JT)

A theorem and its proof on the rationality of the base and exponent of a power, as well as the power itself, are presented. (JT)

Historical background and mathematical development of Riemann's rearrangement theorem are presented. The theorem is stated and proved in two parts. (PK)

A hypothetical classroom discussion is used to present concepts and problems students can master. Three computer programs are listed for binomial probabilities. (MNS)

A questionnaire was given to 167 college students enrolled in business or precalculus mathematics, or statistics. Many had not taken three years of high school mathematics because the courses were not deemed important, were not required, or conflicted with others. Two-thirds felt unprepared for college mathematics courses. (MNS)

Describes a process which allows students to explore repeating decimals without being inhibited by the limitations of the calculator display. In addition, the process can take some of the mystery from the decimal forms of rational numbers. (JN)

The author uses a format in developmental mathematics courses that stresses (1) developing a positive attitude toward mathematics; (2) encouraging activeness on the part of the students; and (3) providing survival skills for nondevelopmental courses that encourage the practice of problem solving and analytical skills. Each of these areas is…

How min-max problems can be solved with trigonometry and without calculus is described. (MNS)

Data from an electrocardiagram are analyzed mathematically in order to determine specific heart abnormalities. The mathematics behind one such problem is explained. (DT)

Symmetry properties of wallpaper patterns are analyzed. (DT)

This material shows how to use basic techniques, principles of counting, and geometry to count squares on geoboards. The methods are elementary in that the proofs are easily conceptualized. A discussion of other approaches illustrates that easily stated problems may lead to very difficult and sophisticated methods. (MP)

The approach discussed intuitively illustrates how a problem can be analyzed by breaking it down into parts. The method makes extensive use of graphs of absolute value functions and is broken down into three stages. Each stage is covered in some detail. (MP)
