Show HN: MathForKids – Interactive App Teaching Simple Math to Kindergarten Kids (mathforkids-seven.vercel.app)

Hello HN,

I just wanted to share this simple React application I built with the help of Claude Sonnet 3.5. This application was designed to teach my nephews basic kindergarten math, specifically addition and subtraction.

I am really amazed at what Claude Sonnet 3.5 can do, especially when it comes to learning new frameworks and building side projects.

By the way I am no expert at React.
