To solve the expression \( 3 + 39 - \frac{38}{2} \), we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

1. First, divide \( 38 \) by \( 2 \):
   \[
   \frac{38}{2} = 19
   \]

2. Now substitute back into the expression:
   \[
   3 + 39 - 19
   \]

3. Add \( 3 \) and \( 39 \):
   \[
   3 + 39 = 42
   \]

4. Finally, subtract \( 19 \) from \( 42 \):
   \[
   42 - 19 = 23
   \]

Thus, the result is \( 23 \).
