Applying Math and Computer Science

Hello! I am going to start a casual thread here asking this wonderful community about their experiences in regards to Mathematics & Computer Science! For those who are experienced in these two fields, what do you guys like about it and why so? Is there anything that you are excited for? What cool things have you created? And most importantly how do you interpret in which the two correlate to each other? I am a Computer Science Major currently and I have found ways to create small projects involving games and I plan to store data in a Database utilizing MongoDB or bravely trying to create my own! Thanks for your time! (edited)
