## Subtracting Binary Numbers

Here you can practice **binary subtraction**. When you press "New Problem,"
**binary** numbers will appear in the first two cells. Enter their difference as a **binary**
number in the third cell and press "Check Answer." Results appear in the second
table.

**Hints**
- If you get a question incorrect, you should redo it and resubmit the answer.
- Do not use "leading zeros". That is, do not input binary numbers like "001101".
