Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

Programing a microcomputer to solve problems in whole-number arithmetic, rather than using the built-in operations of the computer, is described. Not only useful, it also enhances important mathematical concepts and is adaptable to a range of student abilities. (MNS)

Computer games and tutorials for young children are reviewed. These include mathematics and language games, alphabet and number/counting primers, music games, and an arcade game. Program name, format, language, current price, manufacturer, and description are provided for each program reviewed. (JN)

Experiences with complex numbers and graphical representations of them are discussed, with a program for a microcomputer. (MNS)
