Simple math Q

[ebolisa]

// answer = 60/5(7-5) =?6 ?24
a = 60
b = 5
c = 7
d = 5

res = a / b (c - d)

print(res)

Traceback (most recent call last):
File "C:/SharedFiles/Python/practice/temp.py", line 6, in <module>
res = a / b (c - d)
TypeError: 'int' object is not callable

What's up with this simple ecuation?
TIA
