$- 23 - (- 9 \frac{4}{5})$

Step 1

Since there are no variables in the expression, the domain is all real numbers.

${x | x \in ℝ}$

Step 2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
