I'd like to know about MS Office possible alternatives for Gnu/Linux with possibility to write in math mode, that is to write equations; at least angle signs and triangle signs.
I am going to send some midterm problems to students. I expected that they will write the answers in MS Word and all be happy.
But now I realize that not all students have Windows, some of them probably are free persons and have Gnu/Linux on their machines.
I also wanted to see who is an author of the document (in file properties) to prevent cheating.
I can not obligate them to write in LaTeX or something similar.
I need something MS Office like user friendly but with possibility of simple math mode.
