A method of helping students attack the components of mathematics as a language is discussed; examples from arithmetic and from calculus are illustrated. (DT)

Five different methods for determining the maximizing condition for x(a - x) are presented. Included is the ancient Greek version and a method attributed to Fermat. None of the proofs use calculus. (LS)

The author presents a technique for solving limit problems that involve polynomial or rational functions by using delta, epsilon proofs. (MN)

This brief article summarizes the major contributions of several British mathematicians to the development of the calculus. (SD)

Arithmetic combinations of functions and their arguments are discussed, and resulting properties are related to first-year calculus topics. (MP)

Instructions are given for building a flexible model used for illustrating an elliptic paraboloid, a parabolic cylinder, and a hyperbolic paraboloid. (DT)

A method is given for obtaining a fairly accurate table of common logarithms, elementary arithmetic, and linear interpolation. The author recommends the use of a calculator. (Author/MN)

A commonly used computer method of pseudo-random number generation is reviewed along with an example of a program that uses this method in one of its subroutines. (MN)

A theorem concerning the solutions of systems of linear equations is presented. (SD)

Learning activities in statistics are described in which data about students in the class are collected and analyzed. (DT)
