To add the numbers \( 32.8 \) and \( 2.56 \times 10^{-2} \), we first need to convert \( 2.56 \times 10^{-2} \) into standard decimal form:
\[ 2.56 \times 10^{-2} = 0.0256 \]
Now we can add the two numbers:
\[ 32.8 + 0.0256 = 32.8256 \]
Therefore, the result of adding \( 32.8 \) and \( 2.56 \times 10^{-2} \) is:
\[ 32.8256 \]
