Peer reviewedFord, Kevin – Australian Mathematics Teacher, 1978
Early calculating methods and devices are discussed. These include finger products, the abacus, ancient multiplication algorithms, Napier's bones, and monograms. (MP)
Descriptors: Algorithms, Computation, Instruction, Mathematics Education
Peer reviewedSmith, Lehi T. – Mathematics Teacher, 1978
A test for divisibility by any prime number is discussed and its proof is given. (MP)
Descriptors: Algorithms, Division, Instruction, Mathematics
Peer reviewedVenit, Stewart M. – Mathematics Teacher, 1978
Comparisons are made between the errors obtained when approximating the integral with the midpoint rule, the trapezoidal rule, and Simpson's rule. (MP)

Peer reviewedAutrey, Melanie Ann; Austin, Joe Dan – Mathematics Teacher, 1979
An alternate method for factoring quadratic equations is presented as being quicker and easier to use than the trial-and-error method. (MP)
Descriptors: Algebra, Algorithms, Instruction, Secondary Education
Peer reviewedEimer, Rebecca A. – Mathematics Teacher, 1977
An algorithm is given for computing the cube root of any real number on a calculator. (DT)
Descriptors: Algorithms, Calculators, Instruction, Mathematics Education
Peer reviewedEdge, John – Mathematics in School, 1979
Two algorithms are developed for finding the square roots of numbers. One is based on the rule that x square is the sum of the first x odd numbers; the other is algebraic. (MP)

Peer reviewedHancock, Robert R. – Mathematics Teacher, 1976
Identifying the larger (L), smaller (S) and difference (D) of two real numbers, and then selecting the appropriate relationship between L, D, and S can help students solve algebra word problems. (SD)
Descriptors: Algebra, Algorithms, Curriculum, Instruction
Peer reviewedGaslin, William L. – Journal for Research in Mathematics Education, 1975
Descriptors: Algorithms, Attitudes, Calculators, Fractions
Peer reviewedBarszcz, Edward L.; Gentile, J. Ronald – Journal for Research in Mathematics Education, 1976
When two methods of transforming numbers from one base to another were taught sequentially, the first interfered with learning of the second. (SD)
Descriptors: Algorithms, Instruction, Learning, Mathematics Education
Peer reviewedFriedlander, Richard J. – Mathematics Teacher, 1978
Shortcuts to use when performing operations with the calculator are given. Algorithms discussed include reciprocals, powers, parentheses, infinite series, and synthetic division. (MP)
Descriptors: Algorithms, Calculators, Computation, Educational Media
Peer reviewedMathematics Teacher, 1982
The following ideas are shared: (1) a low-stress subtraction algorithm that eliminates the traditional borrowing process, and (2) an approach to graphing circular functions that looks at the process of modifying simple functions as a series of shifting, sliding, and stretching adjustments, with its biggest advantage viewed as its generality. (MP)

Peer reviewedPeelle, Howard A. – International Journal of Mathematical Education in Science and Technology, 1975
Use of the computer programs provided here in APL programming language can help students understand computational algorithms. (SD)
Descriptors: Algebra, Algorithms, College Mathematics, Computer Programs
Peer reviewedWirth, James F. – Mathematics Teacher, 1975
An approach to solving equations is presented. (SD)
Descriptors: Algebra, Algorithms, Curriculum, Instruction
Thomas, F. H. – Mathematics Teaching, 1974
With the advent of computers and electronic calculators, the role of logarithms in the curriculum is changing. An intuitive approach to logarithms, stressing the notion of isomorphism, is discussed. (SD)
