We are given the following expression


(-2)^2+26/(-8+6)\cdot2-(-10)-2^2

Recall that the order of operations (PEMDAS) is given by

1st = P = Parentheses

2nd = E = Exponents

3rd = MD = Multiply or Divide

4th = AS = Addition or Subtraction

Let us follow the above PEMDAS rule to simplify the given expression


\begin{gathered} (-2)^2+26/(-8+6)\cdot2-(-10)-2^2 \\ -2^2+26/-2\cdot2+10-2^2 \\ 4^{}+26/-2\cdot2+10-4 \\ 4^{}-13\cdot2+10-4 \\ 4^{}-26+10-4 \\ -26+10 \\ -16 \end{gathered}

Therefore, the simplified expression is -16
