Discusses the importance of calculators in the teaching and learning of mathematics. Argues that affordable graphing calculators let all mathematics students use computer visualization on a regular basis for both in-class and out-of-class activities. (ASK)

The calculator is used to solve certain formidable equations, which arise naturally and which may be difficult or impossible to solve by standard methods, by a method of successive approximations. (MP)

A program is presented which enables a programable calculator to become a device to check the arithmetic computational skills of students. (MP)

A hand-held calculator is used to explore several easy and interesting mathematical topics involving compound and continuous interest suitable for beginning college students. (MN)

A method for approximating the nth root of any positive number that requires only a four-function calculator with a square-root key and repeat multiplication capability is given. (MN)

Argues that before topics are added to or deleted from the traditional mathematics curriculum, it should be determined how technology can be used to teach that content. (PK)

Illustrated is the use of computer- or calculator-based graphing to deepen students' understanding about solutions to inequalities. Two examples which use a zoom-in procedure are provided. (YP)
