statements.
2. What values are expected from the following operations
(a) (2.0 + 3.0**2) / (8.0-2.0+1.0)
(b) (2.0+3.0)**2 / (8.0-2.0+1.0)
(c) 3.0/5.0 + 2.0 ** 3
(d) 3/5 + 2**3
3. what value do you expect to print after reading this program?
program test
implicit none
real :: x=3.0
integer :: i=7
x = x/(x-1.0)**2**(-1)-1.0
i = i + 1/i-3
print *, x,i
stop
end program test

print:
m = n - (n/2)*2
