Answer:

13 1/6

Step-by-step explanation:

Follow PEMDAS:

(7/2-1/3) * (-2)^2 +1/2

P: parenthesis... 7/2 - 1/3 is 19/6

then you do E: exponents... (-2)^2 is basically -2 * -2 which a negative multiplied by a negative is a positive so its 4.

19/6 * 4+1/2

PE M DAS... M: multiply... 19/6 *4 is 38/3 which simplifies to 12 2/3

Lastly you add 12 2/3 with 1/2 and you get 13 1/6
