To determine if \( 402 + (-928,400) \) is positive or negative, we can simplify the expression:
\[ 402 + (-928,400) = 402 - 928,400 \]
Now, perform the subtraction:
\[ 402 - 928,400 = 402 - 928,400 = -928,400 + 402 = -928,000 \]
Since the result \( -928,000 \) is negative, the final answer is that \( 402 + (-928,400) \) is negative.
