To solve, we use the order of operations PEMDAS, where
P = Parenthesis
E = Exponets
M = Multiplication
D = Division
A = Addition
S = Subtraction
State the expression to be simplified:
Possibility 1

Expanding the parenthesis:

Multiplying then subtracting,

Therefore, the answer is 204.
Possibility 2

Expanding parenthesis:

Multiplying:

Dividing then subtracting:

Therefore, the answer is -179.998.
Possibility 3

Expanding parenthesis:

Multiplying:

Further expanding the parenthesis then dividing:

Therefore, the answer is 0.0018.
