The problem of finding cube roots when limited to a calculator with only square root capability is discussed. An algorithm is demonstrated and explained which should always produce a good approximation within a few iterations. (MP)

Several subtraction algorithms are analyzed to see if they involve borrowing. The main focus is on an analysis of a procedure called the residue method. The operational arithmetic which underlies the symbolic manipulations is examined and conditions where the method does and does not use borrowing are highlighted. (MP)

A program designed to calculate pi using a Monte Carlo simulation based on "throwing darts" at a quarter circle of unit radius inscribed in a unit square is presented. (MP)

A finger method for subtraction that has proved successful with many young subtraction-troubled mathematics students is presented. (MP)

Calculator use by kindergarten and first-grade pupils was examined to see whether they could perceive and use the "counter button." Results indicated pupils at this age could use calculators as a tool, and further research is encouraged. (MP)

Some techniques for developing the ability to multiply and divide by powers of ten with ease and understanding are presented. (Author/MK)

Describes the accomplishments and life of the gifted Chinese mathematician Hua Lo-Keng. Hua is noted for his efforts in popularizing mathematics and for his work in number theory, in particular his contributions to Waring's problem. Hua has published 150 papers in respected journals and is the author of nine books. (Author/DS)

This is a review of the current research in mathematics involving breadth of ideas. Research includes topics in number theory, classification of all finite simple groups, the representation of group aids in their application to the study of symmetry. (Author/SA)

Five intuitive explanations of division by zero that arise from the common models used in the elementary school to introduce whole number division are presented. (MK)

Some history, applications, and unique characteristics of zero are discussed. (MK)

Masters of worksheets designed to generate interest in mathematics and provide mathematical experiences that lead to the introduction of the concept of a variable are presented. (MK)

Curricular placement of and emphasis on common and decimal fractions are discussed. Suggestions include: retaining common fractions in the curriculum, teaching decimal concepts and notation earlier, reducing fraction computation complexity, and moving fraction computation upward in the curriculum. (MK)

Written for teachers of "liberal arts physics," this article about logarithms outlines a way to review arithmetic skills in manipulating powers, discusses the attitude of physicists toward numbers, and gives an introduction to estimation. (MK)

A method is presented for determining cube roots on a calculator with square root facility that has a rapid rate of convergence. (MP)

An activity leading to the discovery of a property of primes is suggested for encouraging algebra students to make nontrivial conjectures. (MP)
