Answer:
Darius took (17-2)^2 instead of 17-2^2, ignoring the order of operations. The answer is 13.
Step-by-step explanation:
To solve 17-2^2, Darius should first square two, then subtract that from 17. By subtracting 2 from 17 first, you ignore the PEMDAS rule (parenthesis, exponents, multiplication/division, addition/subtraction).
2^2=2
17-4=13
