27 + 12 - 32 - 8

27 = 3*3*3 = 33

12 = 2*2*3 = 23

32 = 2*2*2*2*2 = 42

8 = 2*2*2 = 22

33 + 23 - 42 - 22

Here is where I get sort of confused. Because the like terms are 3. And so Im supposed to add them and I get 53. Then I subtract the 42 - 22 and I get a 22, but its supposed to be 6.(would that be known as the index? And can indexes be negative??
