To evaluate, apply the order of operation known as PEMDAS.

So, do the operation inside the parenthesis first.

Since 4-3=1, then the expression becomes:


Next, do the operation indicated by the given exponent.


Notice that the remaining operations are subtraction and multiplication. Since multiplication comes before subtraction in PEMDAS, the next step is to multiply 2 and 1.


And then, subtract.


Hence, `5^2-2(4-3)=23` .
