#1**-1 **

Doing this you must follow the ** pemdas** method which is

*P - Parenthasses*

*E - Exponets*

*M/D - Multiplication/division *

*A/S - Addition and sutraction *

So, were given the equation \(2 + {3}^{2} - (3 - 1)\)

So in pemdas it first states we must do the parenthasses so will start with subtracting 1 from 3 ( 3 - 1) = 2

Our equation now is \(2 + {3}^{2} - 2\)

Next step in pemdas is do the exponets and there are exponets so we can take care of that 3^{2} Is 3 * 3 = 9

So we can add that to our equation \(2 + 9 * 2\)

Now we know that multilcation is the next step in the pemdas process so we need to multiply 9 times 2 and 9 * 2 = 18

and all that's left is \(2 + 18\)

And 2 + 18 = 20

So, the value to the expression is 20
