Arndt, A. B. – Mathematics Teacher, 1983
Facts are given about the ninth-century Arab mathematician Al-Khwarizmi, from whose name the word algorithm is derived. His influence on algebra and arithmetic are discussed. (MNS)
Descriptors: Algebra, Algorithms, Arithmetic, Biographies
Hadar, Nitsa – Mathematics Teaching, 1979
Suggestions for teaching the concept of division by zero are given. (MK)
Descriptors: Algorithms, Division, Elementary Secondary Education, Mathematical Concepts

Leutzinger, Larry P.; Nelson, Glenn – Arithmetic Teacher, 1980
Some techniques for developing the ability to multiply and divide by powers of ten with ease and understanding are presented. (Author/MK)
Descriptors: Activities, Algorithms, Division, Elementary Education

Davies, H. B. – International Journal of Mathematical Education in Science and Technology, 1980
Attention is drawn to an ancient Greek method for finding the least common multiple (LCM) of two numbers. A link is established between this method and a well-known method of obtaining the highest common factor (HCF) numbers. This leads to consideration of some relationships between HCF and LCM. (Author/MK)

Trotter, Terrel, Jr.; Myers, Mark D. – Arithmetic Teacher, 1980
An activity is presented which provides a novel approach to number patterns, experience in following an unusual algorithmic procedure, and practice in systematic search techniques and basic facts. (MK)
Descriptors: Algorithms, Elementary Education, Elementary School Mathematics, Mathematics Curriculum

Markowitz, Lee M. – Mathematics Teacher, 1983
Variations on a card trick are noted, with a formula for generalizing them. Another trick which can be proved with algebraic principles is then presented. (MNS)
