Four computer programs (Applesoft Basic) on prime numbers are described, including programs for factoring a positive integer as a product of primes, listing all divisors of a given A, and for exploring primes representable as prescribed sums/differences involving squares, cubes, Fibonnaci numbers, or other primes. Program listings are included.…

Programing a computer to list subtraction palindromes is discussed. Sample programs and output are included. (MNS)

Least-squares line fitting is developed without calculus. Its rationale and an example with consumption patterns are provided. (MNS)

Worksheets are provided to help students visualize, identify, and describe the solids generated by rotating polygons about axes in various positions, to relate these figures to cylinders and cones, and to compute their surface areas and volumes. (MNS)

Excerpts from the April 1950 issue of this journal, focusing on the teaching of geometry, are presented. The concern is its lack of importance in the curriculum. (MNS)

The non-Euclidean taxicab geometry is described and contrasted with Euclidean geometry, with examples teachers could use with students. (MNS)

An interesting, alternative proof for an arithmetic series is developed in detail. (MNS)

Highlights from previous studies and results from surveys of teacher placement offices, secondary school administrators, and teachers all show a severe shortage of qualified secondary school science and mathematics teachers. (Author/MLF)

The article presents and discusses an optimization problem concerned with observing objects from a moving car. (MK)

A graphical representation is used to construct a line one centimetre in length. (MP)

A math teacher suggests redesigning geometric studies to emphasize career education. (Editor)

Four unusual mathematics problems with interesting routes to solution are presented. A general method of solution to problems of this type is proposed. (MP)

Ways of using the calculator as a vehicle for investigating one aspect of the square root concept are illustrated. (MK)

A method for sketching functions and finding slopes and roots rising synthetic division is illustrated. (MK)

A generalized method of synthetic division where the divisor polynomial may be of any degree equal to or larger than 1, and the dividend polynomial may be of equal or larger degree than the divisor polynomial and a generalization of the familiar remainder theorem, are presented. (Author/MK)
