Subtract 3829 from 9324.

• A. 5490
• B. 5495
• C. 5500
• D. 5485

Answer: (B)

Subtracting 3829 from 9324 means do 9324 minus 3829, using borrowing when a digit on top is smaller than the digit below it.

Look at the units: 4 is less than 9, so borrow 1 from the tens place. The units become 14 and the tens drop to 1. 14 − 9 = 5.

Now the tens place has 1, which is less than 2, so borrow from the hundreds. The tens become 11 and the hundreds drop to 2. 11 − 2 = 9.

In the hundreds place, 2 is less than 8, so borrow from the thousands. The hundreds become 12 and the thousands drop to 8. 12 − 8 = 4.

Finally, 8 minus 3 in the thousands place equals 5.

Putting the digits together gives 5495.
