There are around 8 written problems which I need the solution to. I'll send pictures of the problem at dec 16 5:00 pm est and I need all answers by dec 16th 9:15 pm est but also answers as each question is finished.

I'll provide some reference problems and content to look at so the freelancer has idea of what kind of questions and related topics will be asked.
