1 230 - 199 =
Correct Answer
B. 1131
Explanation
To find the difference between 1,230 and 199, we subtract 199 from 1,230. When we subtract, we start from the rightmost digit and work our way left. In this case, 0 minus 9 is -9, which we cannot do without borrowing. So, we borrow 1 from the thousands place, making it 10. Now, 10 minus 9 is 1, and we write down 1 in the ones place. Moving to the next column, 2 minus 9 is -7, again requiring borrowing. We borrow 1 from the hundreds place, making it 1. Now, 11 minus 9 is 2, and we write down 2 in the tens place. Finally, 1 minus 1 is 0, and we write down 0 in the hundreds place. Therefore, the correct answer is 1,131.
