Abstract: A system to teach mathematics using virtual musical instruments displayed on a client computing device includes a server, a database stored on the server, an application stored on the server, and a plurality of songs stored on the server. The system also includes a plurality of mathematical equations stored in the database, where each mathematical equation comprises a composite of musical notes and mathematical operators. The system includes a local application stored on the client computing device to display the virtual musical instrument and is configured to display a correct indicator in response to the user solving the mathematical equation correctly when the user plays a musical note on the virtual musical instrument corresponding to the numerical answer that correlates to the song.
