Patterns are a ubiquitous phenomenon. They exist in nature's plant species emerging as a complete order from truncated matter. Patterns are also present in the fine arts where the aesthetic properties of form exist and conjugate through paintings and sculptures. Mathematical patterns, the focus of this position paper, dominate financial scenarios,…

"The Language of Mathematics in Science" is an ASE/Nuffield project aimed at supporting teachers of 11-16 science in the use of mathematical ideas in the science curriculum. Two publications have been produced. This article focuses on the first of these, "The Language of Mathematics in Science: A Guide for Teachers of 11-16…

In this article, we explore the game based on the following problem from the 1st Mathematical Olympiad of Central America and the Caribbean, held in Costa Rica in 1999: Player A turns on the calculator, presses a digit key and then presses the + key. A second later, player B presses a digit key in the same row or column of the last digit key…

Illustrated is the use of pocket calculators for solving the Francis formula for rectangular, triangular, and V-notched weirs. (CS)

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)

The calculator is used to solve certain formidable equations, which arise naturally and which may be difficult or impossible to solve by standard methods, by a method of successive approximations. (MP)

Describes the development of computers and calculators, noting intitial resistance to and later acceptance of calculators in the classroom. Advocates teaching children to perform simple calculations and stresses estimation skills over speed and accuracy for doing long, complicated computations. Includes recommendations for classroom calculator use…

Repeatedly taking the square root with a calculator yields numbers with logarithmic-type properties, which can be used to define the logarithm functions. (MP)

Computation errors that may occur by expanded use of calculators are discussed. Potential errors with five exact arithmetic examples are described as they are translated into approximate processes. (MNS)

Surveys the range of electronic calculators currently available and their capabilities. Prices range from $20.00 to $800.00, and functions performed range from the four arithmetic operations to complex operations such as the computation of standard deviation, vector addition, and programs with up to 100 steps. (MLH)

Shortcuts to use when performing operations with the calculator are given. Algorithms discussed include reciprocals, powers, parentheses, infinite series, and synthetic division. (MP)

Describes one program each for performing Fourier analysis and synthesis with a Hewlett-Packard HP-25 calculator. (MLH)

Suggests and illustrates ways in which systematic consideration of selected unary operations can be facilitated by using electronic calculators. Emphasis is placed upon unary operations suitable for exploration and investigation at the pre-algebra level, using calculation algorithms as a basis for generating examples and non-examples to develop…

The appropriateness of existing instructional materials for three calculators designed for use by the visually impaired was assessed with 15 blind and partially sighted Ss (15-21 years old). (Author/SBH)
