| Abstract | A procedure is described that enables students to perform operations on fractions with a calculator, expressing the answer as a fraction. Patterns using paper-and-pencil procedures for each operation with fractions are presented. A microcomputer software program illustrates how the answer can be found using integer values of the numerators and denominators of fractions. An adaptation of this computer program is used to devise a method for using calculators in work with addition of fractions. First, some old algorithms and an explanation of Euclid's Algorithm are given as background for understanding the calculator procedure. Then the steps in that procedure are listed, stressing that multiplication, division, and subtraction of fractions can be performed, as well as addition. (MNS) |
