12 - {20 - 2(6² / 3 x 2²)]
i got -912
is that right?

If that little illegible symbol is a superscript two then you aer very wrong.
6^2 is 36 and 2^2 is 4.
So the problem is 12-(20-2(36/(3 x 4))
That is 12-20+6
And finally that is 18-20 = -2

1st interpretation:
= 12 - (20 - 2[6² / {3 * 2²}])
= 12 - (20 - 2[36 / {3 * 4}])
= 12 - (20 - 2[36 / 12])
= 12 - (20 - 2[3])
= 12 - (20 - 6)
= 12 - (14)
= 12 - 14
= - 2
2nd interpretation:
= 12 - (20 - 2[{6² / 3} * 2²])
= 12 - (20 - 2[{36 / 3} * 4])
= 12 - (20 - 2[12 * 4])
= 12 - (20 - 2[48])
= 12 - (20 - 96)
= 12 - (- 76)
= 12 + 76
= 88
Answer: definitely - 912 is not right.

I got -2
First solve everything that is squared, then everything in the ( ), the everything in the [ ], then solve.
So, 2² = 4 and 6² = 36, then
3 x 4 = 12, which gives you
36/12 = 3, which leave you with 12- [20 - 2(3)]
next, 2(3) = 6,
12- [20 - 6]
12- [14]
12-14 =
-2
Hope it helps.

I solved and ended with 88.
12 - [20 - 2(36/3 x 4)]
12 - [20 - 2(48)]
12 - [20 - 96]
12 - [-76]
88

Remember order of operations (PEMDAS)- parenthesis, exponents, multiplication, division, addition, subtraction.
= 12 - [20 - 2(36/12)]
= 12 - [20 - 2(3)]
= 12 - [20 - 6]
= 12 - 14
= -2

12-(20-2(3))
12-(14)=-2
this problem is not set up logically so no wonder it was hard to solve
