feat:adds mattieweathersby letter D equation homework

[mattieweathersby]

BOYYYYY!!!!! This was difficult!!! I could not for the life of me grasp what I was doing because seeing the letters in place for some reason made me feel like I couldn't figure it out unless there were numbers to substitute it. But after the help from some fellow comrades, I was able to grasp what was going on. I would definitely like to do something like this again so the information can stick.

The calculate method in expression_calculator.ts was implemented correctly, using helper methods for addition, subtraction, multiplication, division, and power operations. This modular approach enhances readability and maintainability. The .env.test file was also correctly configured with the assigned group letter 'D', ensuring compliance with the assignment's requirements. From a technical perspective, the code is well-structured and adheres to TypeScript standards, with consistent style and no syntax errors. All GitHub checks passed, indicating the code is robust and free of issues. However, there was no attempt to tackle the stretch assignment, resulting in a stretch score of 0. Overall, excellent work on the main assignment, with room for further exploration in the stretch tasks.
