yes.

if you work in the perethese first and work out you will see that it cancle each other out.
Example: 6(3to the 2nd power+2)-11=55
3x3=9
6(9+2)-11=55
9+2=11
6(11)-11=55
66-11=55
55=55
55 on the left becomes negative then it goes to the 55 on the right.
55 -55= 0

yes. . . remember PEMDAS

Prentheses (3 to the second is 9 +2 is 11)
Eponents in this case its in the prentheses so its done
Multiply 6 times 11 = 66
Divide there is none
Add it was in the prentheses so its done allready
Subtract 66 - 11 = 55

6(3²+2)-11 = 55
Calculate Exponents:
6(9+2)-11 = 55
Remove brackets:
54 + 12 -11 = 55
54 + 1 = 55
Correct

Umm, yeah I think it is. I'm sure it is O.O
Because...PEMDAS.
I did, 3 squared first which is 9.
so it'd be 6(9+2)-11
then I did 9+2 which is 11.
So it'd be 6(11)-11.
Next, I multiplied which would make it 66-11.
And 66-11=55 :]
