Three different 6th grade classes are combining for a square dancing unit.  If possible, the teachers would like each male student to partner with a female student for the unit.  The first class has 17 males and 13 females, while the second class has 14 males and 18 females, and the third class has 15 males and 17 females.  When the classes are combined, how many students will be unable to partner with a student of the opposite gender?
How many males are in the three classes? ** Combining the three classes, there are 17 + 14 + 15 = <<17+14+15=46>>46 male students.
How many females are in the three classes? ** Similarly, there are 13 + 18 + 17 = <<13+18+17=48>>48 female students.
