I think literally everyone is getting this wrong; haven’t seen a single right answer. Yes it is PEDMAS, but everyone is missing out the ! after the 0. 0! (Ie nought factorial) = 1. So the answer is (11 11) (11x11) (11x1) = 22 121 11 = 154.
PEDMAS
Imagine parentheses around both the numerator and the denominator.
With no actual parentheses, solve exponent first.
10² = 100
Subtract left to right.
-100
-100 - 10 = -110
Then divide.
-110 ÷ 10 = -11
Answer: -11
