Sabina Shehaj Calculus 2 Capstone Seminar At this math lecture there were 6 students presenting their projects for their senior capstone seminar. The only presentation that I found interesting was by Lindsey Platt. She talked about the existence of infinity of ½ Smith numbers. A Smith number is a composite number for which, in a given base (in base 10 by default), the sum of its digits is equal to the sum of the digits in its prime factorization. For example, 378 = 2 × 3 × 3 × 3 × 7 is a Smith number since 3 + 7 + 8 = 2 + 3 + 3 + 3 + 7. It's important to remember that, by definition, the factors are treated as digits.

Her presentation got me interested in maybe learning and researching more about Smith numbers. The other presentations were things that I didnt understand what they were and what was the main point of them. I enjoyed all of the presentations and the knowledge that I gained from the lecture. This lecture was filled with students and a few mah teachers that took notes throughout the presentations....
