##### Discrete Mathematics

Extending al-Karaji’s Work on Sums of Odd Powers of Integers, by Hasan Unal and Hakan Kursat Oral
The authors share their discovery of an 1867 article in a Turkish scientific journal that extends al-Karaji’s famous formula for the sum of the cubes to sums of higher odd powers, with suggested exercises.

Primary Historical Sources in the Classroom: Discrete Mathematics and Computer Science
A collection of projects designed to help students learn concepts in discrete mathematics, combinatorics, linear algebra and computer science by studying primary historical sources, with an overview of the benefits of this approach to teaching and learning. Includes the following specific projects suitable for use in Discrete Mathematics.

Sums of Powers of Positive Integers, by Janet Beery
A history of attempts to develop formulas expressing the sums of powers of the first n positive integers from the Pythagoreans to Jakob Bernoulli, with exercises (and their solutions) for students.
