Hello,
I have a Ph. D. in Mathematics.
I worked at various institutions, as a Teaching Assistant and as an instructor, such as Ohio State University, University of İllinois at Urbana-Champaign and Middle East Technical University, Ankara, Turkey.
I will write the answers in Latex (if you are not familiar with the term Latex, it is a type_setting program for math among others. The output is in pdf format, but it can be changed to another format easily).
.
Since I do not know the particulars of the job, my bid is tentative
