Question

what does "roster" mean?
Ms. Sue
Roster is a list of people. For instance each class in school has a roster showing the names of the students enrolled in that class.

what does that have to do with math?
Ms. Sue
I don't know. Why did you ask the question? Do you have a problem that mentions "roster?"
robin
it was a vocabulary word
Ms. Sue
Ok. The only connection I can see with math is that a problem may refer to a roster -- such as 40% of the class roster of 30 students are males.
