This paper was written as a discussion guide for participants at an Australian conference. How calculators and computers might affect the curriculum is discussed, with questions focused on what mathematics should be taught, when, why, where, and how. (MNS)

Examples are given of how calculator-sized pocket computers, which can receive, store, and execute BASIC programs, can be used in mathematics classrooms. (MNS)

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)
