In the problem \(99 + 1 \times 4\), there is only multiplication and addition.
According to PEMDAS, multiplication comes before addition. So you do that first.
\(1 \times 4 = 4\)
Now you add 4 and 99 to get your answer.
\(99 + 4 = 103\)
The answer is \(\boxed{ 103 }\).
However, it looks like in your question the 99+1 is separated from the 4. If the question was originally \((99 + 1) \times 4\) then we do the parenthesis first. 99 + 1 = 100. \(100 \times 4 = 400\).
So depending on your question,
\(99+1\times4=\boxed{103}\)
\((99+1)\times4=\boxed{400}\)
