UnSOLVED: Egyptian Fractions

The problems posed in this book focus on the way ancient Egyptians used fractions. They expressed fractions as the sum of distinct unit fractions. Many mathematicians are curious about Egyptian fractions. In this book, you will find conjectures by Robert H. Breusch, Ernst G. Straus, Paul Erdős, and an algorithm from Fibonacci, all utilizing Egyptian Fractions. The work leans heavily on common denominators, factors, multiples, equivalency, and adding and subtracting fractions. Some work with prime and composite numbers also appears. Children and adults will explore patterns, structures, and relationships within this mathematical mystery by applying elementary math concepts. What exactly is unsolved in these Egyptian Fraction problems?
