This describes table of contents for one of the author’s unpublished books titled, Mathematical Encounters for the Inquisitive Mind. Mathematical Encounters for the Inquisitive Mind has more than 200 pages and was typeset with Tex/Latex program developed by Professor David Knuth (of Stanford University) and Leslie Lamport respectively.

Perfect, Friendly Numbers: Mathematical Puzzles That Still Challenge

The mathematicians of ancient Greece attributed characters to numbers and awarded some of the status of perfection. For Euclid, one of the finding fathers of modern mathematics, a perfect number was one that equaled the sum of its own divisors – that is numbers that will divide into it without leaving a remainder. The first perfect number is 6: its divisors are 1, 2, and 3, 14 which add up to 6. The second is 28 (1 + two + four + seven + 14). The Greeks knew only two other perfect: 496 and 8,128.
