A method is given for obtaining a fairly accurate table of common logarithms, elementary arithmetic, and linear interpolation. The author recommends the use of a calculator. (Author/MN)

Described is a sequence of calculus courses utilizing the computer to enhance concepts and ideas in calculus. (JLH)

A theorem concerning the solutions of systems of linear equations is presented. (SD)

Computer simulation provides an effective vehicle for teaching many concepts, especially in probability and statistics. Described is a simulation for the applicability of the t distribution to the estimation of a population mean when the standard deviation of the population is unknown. (MNS)

Properties of the arithmetic mean and the geometric mean are discussed, with an analogy between additive multiplicative averages. Drawing analogies between symbols and relations is proposed as a way of strengthening students' understanding and enriching the study of elementary statistics. (MNS)

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

Develops search patterns for locating an object which may be in one of several locations. (JP)

Two approaches are discussed for calculating the work necessary to pump water from a conical or parabolic container. The direct method derived from the definition of work is easy to misuse, as illustrated by a student's incorrect solution. (JP)

The relationship of the harmonic mean of two positive real numbers to the geometric mean and to the arithmetic mean is discussed; two geometric constructions for the harmonic mean are given. (DT)

How far does the back end of a bus swing out as the driver makes a turn at an intersection?'' is the problem discussed. (MM)
