This is incorrect.

The "proper" (if somewhat ambiguous, given the context) grouping is:

6-(1$\times$0)+(2$\div$2)
 
Yes, it is 7. And people on Facebook keep using this kind of "riddle" to gain likes and shares to increase their accounts' web traffic. It is a bit better rather than showing some suffering people in third world countries, though.

Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
