The title sums it up pretty well. I'm using MS Word to write a paper I intend to publish in a SCI journal. It will contain ~15 equations (non-trivial ones: integrals, sums, fractions, special characters, etc.). I'm fairly efficient in Word, but have absolutely no experience using LaTeX. Please correct me if I'm wrong, but I'm under the impression that once a paper is accepted, it is edited to conform with the journals publishing style, as opposed to some conferences, I attended, which provide a pre-formatted Word document in which I have to place my work before applying to the conference. As the journal provides no such template (but accepts .doc format), I was wondering if there could emerge any issues regarding the equations.
PS: the field is computer science
