#### Answer

$583-279=304$

#### Work Step by Step

Working left to right, subtract the corresponding digits in each place value. If necessary borrow 10 from the next higher place value position to avoid a negative result.
$\ \ \ 583$
$\underline{-279}$
Borrow from the tens postion and subtract $13-9=4$
The subtrahend in the tens position is now 7. Subtract $7-7=0$
The subtrahend in the hundreds position is 5. Subtract $5-2=3$
Write the result of each subtraction in its proper position for its place value. The zero in the tens position cannot be dropped.
