-49

Step-by-step explanation:
-34\text{ + 21 - 39 -(-3)}

Expanding the parenthesis:


\begin{gathered} mu\text{ltiplication of asme sign gives a positive number:} \\ -34\text{ + 21 - 39 + 3} \end{gathered}

simplify:


\begin{gathered} =-34\text{ - 39 + 21 + 3} \\ -34\text{ - 39 = - 7}3 \\ 21\text{ + 3 = 24} \end{gathered}
\begin{gathered} -39\text{ - 39 + 21 + 3 = -73 + 24}| \\ =\text{ }-49 \end{gathered}
