MUs= 8  
m=25
s=24
math only= m-mUs
               = 25-8
               =17 students... answer
science only= s-mUs
                    =24-8
               =16 students.....answer
checking;
union= matth only + mUscience (intersection math and scie.) + scie only
            17 +8 +16
union =41 students.
