Seven articles present: 1) a solution to a force equilibrium problem, 2) a magic square, 3) a characteristic of right triangles, 4) a family tree of Pythagorean triples, 5) a misunderstanding which may be cleared through modern mathematics, 6) a technique for solving conversion problems, and 7) a special permatation problem. (RS)

Six short articles concerned with mathematics education are included. (FL)

Report of an experiment which investigated the use of a programed elementary algebra text as a teaching method. The method was evaluated on the basis of student evaluation of the course and the percentage of students achieving a grade of C or better. Results indicated that the use of programed texts was superior to the traditional approach using…

A collection of mathematical notes - On the Roots of a Certain Determinantal Equation", A Geometrical Look at the Square Root of Pi", and others. (RP) A class of Second Order

A few examples are discussed of situations where some solution to writing a computer program for an algorithmic problem is immediately evident, but the best solution is some distance away. (MP)

An example is given of a lesson that mixes the manipulative skills of algebra with some problems and concepts of calculus; namely, the determination of tangent lines and extrema using synthetic division. (MP)

An example is given of a problem-solving approach by outlining the development of a generalization of the Pythagorean Theorem as applied to points on a unit circle. (MP)

A discrete version of L'Hopital's Rule is presented, with a proof. This version enables one to evaluate the limit and handle other similar problems. (MNS)

In this article, the author takes up the special trinomial (1 + x + x[squared])[superscript n] and shows that the coefficients of its expansion are entries of a Pascal-like triangle. He also shows how to calculate these entries recursively and explicitly. This article could be used in the classroom for enrichment. (Contains 1 table.)
