About the Number 29 (Twenty-nine)

Roman numerals don't seem to go away and the task of writing a program to convert Roman numerals to decimal numbers (and vice versa) is still on MathBabbler's to-do list.

XXIX 1st digit X is 10 2nd digit X is 10 3rd digit I is 1 and the 4th digit X is 10; since the 3rd digit is less than the 4th digit, the 3rd digit is subtracted from the 4th digit XXIX = 10 + 10 + -1 + 10 = 29This BAB is not about Roman numerals; instead, MathBabbler noticed that he didn't have a BAB about the number 29, so that is what this BAB is about.
