Evaluate 8- m/n+p ^2 when m=8 n=2 p=7

8-m/n+p^3= 8-8/2+7^2       sub in the numbers for the variables
(8-8)/2+7^2                         Exponents
(8-8)/2+49                           add the denominators together
(8-8)/60                               subtract 8-8
0/60                                     is the answer (which doesn't seem right to me)
