This paper concerns the derivation of a closed form for a function f(x) given closed forms for f(g(x)) and g(x). (SD)

The author derives a method for direct computation of interest and loan payments. (SD)

Directions are given for using a gravity protractor in constructing an instrument for finding derivatives. (DT)

The system of Gaussian integers is explained, and a new set of integers is derived. (DT)

Misconceptions which students have about the convergence of an alternating series are identified, and counterexamples are provided for each of the misconceptions. (DT)

A statistic giving the maximum error of proportion is derived and applied to problems concerning TV ratings, sample size, and election polls. (DT)

Examples are given of difficulties that students have in determining extrema of real-valued functions of real variables. (DT)

Correlation statistics were computed between class size and drop-out rate for mathematics classes in two suburban community colleges. Correlations were near zero. (JP)

References dealing specifically with college remedial mathematics programs fall into several categories: descriptions of programs at individual colleges, regional surveys, and comparative studies on the relative effectiveness of various modes of instruction. (MN)

A procedure for solving absolute value inequalities involving a distance interpretation is presented. (MN)

The author shows how changing the restriction context of "Fermat's Last Theorem" alters the statement of impossibility. (MN)

The author presents a method of teaching the concept of limit. (SD)

The need for realistic applications to be included in mathematics courses is stressed. Several general examples of realistic problems are suggested. (DT)
