The history of the development of logarithms is traced. (DT)

Articles on the factorization of polynomials using a rejection theorem; a general formula for the N-th of a sequence; and integration by undetermined coefficients. (MM)

The problem of getting a correct result when a fraction is reduced by cancelling a digit which appears in both the numerator and the denominator is extended from the base ten situation to any number base. (DT)

The author shows that the set of all sequences in which each term is the sum of the two previous terms forms a vector space of dimension two. He uses this result to obtain the formula for the Fibonacci sequence and applies the same technique to other linear recursive relations. (MM)

The minimum number and type of whole-unit weights needed to balance any object is extended to the situation where weights may be placed on both pans of a balance scale. (DT)

A problem concerned with a ball on a billiard table is discussed. A theorem and corollaries regarding the path of the ball are formulated and proved. (MK)

This article treats aspects of Gaussian integers that form a setting in which students can generalize concepts from elementary number theory. (DT)
