Example Question #4 : How To Find Order Of Operations

Possible Answers:

Correct answer:

Explanation:

This looks daunting as one long equation, but let's look at each piece and then add them all together. 

23 = 1/23 = 1/8

250 = 1

(–218)1 = –218

6251/4 = 5

(–27)1/3 = –3

Then, 23 + 250 + (–218)1 + 7/8 – 6251/4 + (–27)1/3 = 1/8 + 1 – 218 + 7/8 – 5 – 3 = –224.
