The number Pi (approximately 3.14159) is defined to be the ratio C/d of the circumference (C) to the diameter (d) of any given circle. In particular, Pi measures the circumference of a circle of diameter d = 1. Historically, the Greek mathematician Archimedes found good approximations for Pi by inscribing and circumscribing many-sided polygons about this circle, and calculating their perimeters. Since Pi stands for an infinite decimal, for practical purposes it is useful to find fractions which have a value close to Pi. In this article, the author presents several examples of Pi division and addition problems.
