Evaluate the expression below and determine the real part of the result; then enter the answer in the field below (enter a numerical value only) -13 + 9i


The expression you provided is:

\[
-13 + 9i
\]

This is a complex number, where:
- The real part is **-13**
- The imaginary part is **9i**

You are asked to determine the real part of the result. The real part of the complex number is simply the coefficient of the non-imaginary part, which in this case is **-13**.

Thus, the real part of the expression is:

\[
\boxed{-13}
\]
