Describes a program written in BASIC, called BIGNUM, that was designed to aid in handling big numbers. The program adds, subtracts, multiplies, divides, and raises to a power integers of up to 1024 decimal digits and is thought to be usable on many types of machines. (MP)

A proof is given that for any four digit number, repeated reordering of digits and subtraction will evenutally result in the number 6174. A computer program is included. (DT)

A computer program which produces a print-out of one million items is given in elementary Fortran. Observations of the print-out help students relate to such a large-number concept. (JT)

Explorations of Pascal's triangle through computer programming are described. Programming offers different methods and techniques that enrich the topic. (MNS)

Factorials are discussed, with note of the enormous size on n! even for modest values of n. A recreational problem to determine the number of zeros at the end of numbers such as 10,000! is given, with a computer program. (MNS)

This column includes the description of a game involving addition and subtraction of integers represented by colored bricks, a general formula for an enlargement in the Cartesian plane, an analysis of the possibilities for certain games of board Solitaire, and a BASIC program for a recreational mathematics problem. (DT)

The design of a computer program to efficiently generate prime numbers is discussed. Programs for many different brands of home computers are listed, with suggestions of ways the programs can be speeded up. It is noted everyone seems to have a favorite program, but that every program can be improved. (MP)
