Nicol Tatiana Sanchez De Paula contributed to the danna3851/software10b repository by developing a Basic Arithmetic Demo Program in Java, showcasing core arithmetic operations and utility calculations such as temperature conversion, geometric formulas, and simple financial computations. Her approach emphasized clean code organization, variable declaration, and console output, resulting in a self-contained structure suitable for educational use and future extensibility. In addition to coding, Nicol expanded the repository’s data asset catalog by uploading binary documents, establishing traceable workflows for analytics and data completeness. Her work demonstrated foundational programming skills and addressed both code and data needs within a short project period.
