Summing It All Up: Pre-1900 Algorithms.
Peer reviewed Peer reviewed
Pearson, Eleanor S. – Arithmetic Teacher, 1986
Computational algorithms from American textbooks copyrighted prior to 1900 are presented--some that convey the concept, some just for special cases, and some just for fun. Algorithms for each operation with whole numbers are presented and analyzed. (MNS)

Developing the Subtraction Algorithm
Peer reviewed Peer reviewed
Cleminson, Robert A. – Arithmetic Teacher, 1973
Descriptors: Algorithms, Elementary School Mathematics, Instruction, Mathematics Education
Addition through Palindromes.
Peer reviewed Peer reviewed
Nichol, Margaret – Arithmetic Teacher, 1978
Reviewing addition through the use of palindromes is discussed. A rule for converting any number into a palindrome is presented. (MP)

Method or Justification?
Peer reviewed Peer reviewed
Quast, W. G. – Arithmetic Teacher, 1972
A distinction is made between an algorithm and the justification for the algorithm. Examples of both are given for the operations with whole numbers. (DT)

Low-Stress Subtraction
Peer reviewed Peer reviewed
Hutchings, Barton – Arithmetic Teacher, 1975
A new subtraction algorithm is described and illustrated. Research by the author has shown the method to be easier for low achievers, as well as useful as enrichment for average students. (SD)

Tucker, Benny F. – Arithmetic Teacher, 1973
Descriptors: Algorithms, Decimal Fractions, Division, Elementary School Mathematics
Understanding the Russian Peasant
Peer reviewed Peer reviewed
Reardin, C. Richard, Jr. – Arithmetic Teacher, 1973
A rationale is given for the Russian-peasant algorithm for multiplication indicating why it works as well as how it works. (DT)

The Russian-Peasant Algorithm: Rediscovery and Extension
Peer reviewed Peer reviewed
Boykin, Wilfred E. – Arithmetic Teacher, 1973
The Russian-peasant algorithm for multiplication is described and then extended to developing an algorithm for renaming base ten numbers in other number bases. (DT)
Descriptors: Algorithms, Elementary School Mathematics, Instruction, Mathematical Enrichment
The Fourth Operation is not Fundamental
Peer reviewed Peer reviewed
Zweng, Marilyn J. – Arithmetic Teacher, 1972
The role of division of whole numbers in problem solving and the implications for teaching division computation are examined. Deleting the teaching of division facts, and obtaining solutions by using multiplication facts, is advocated. (DT)
