My community college courses do not use plus/minus grading system. The college I want to transfer does use plus/minus calculation for GPA. Does this mean they will factor an 82 (B) grade at my school as a (B-) at their school and thus my GPA would be according to this new standard?
Probably. Email the college and ask.
Oftentimes when you transfer only the credit transfer in and not the grade (it appear on the transcript as a passed class from another college). You should contact the school you are transferring into and ask their policy.
