Stumped on a math puzzle

[u/StellarisFanatic]

I've been presented with a math puzzle that I can't seem to solve.  The puzzle is a variation of the old game of "24" that used to come on cards.  There are six input numbers, and 4 operations allowed.  Each input and each operation may only be used once.  Order of operations applies, so multiplication and division are processed before addition and subtraction.  The six inputs are:

6, 9, 11, 12, 25, and 27.

The 4 allowed operations are:

addition, subtraction, multiplication, division.

The puzzle:  Using each input and each operation no more than once, and following the standard mathematical order of operations, find a way to get the result of 12. At least one operation must be used.

What is the solution? Is there a standard way beside brute force to find the solution?

Thanks

9-12/6x11+25 or 25-12/6x11+9

Thank you! I think I missed the idea of putting a product of 3 inputs in the middle between addition and subtraction.

Can't use operations more than once.

Are parentheses allowed? 

(9×11-27)÷6

Sadly, no. So this answer actually looks like (9x11)-(27÷6)=94.5
