- Set up the problem:
Write the numbers vertically, with the larger number on top.
Align the numbers by place value (ones, tens, hundreds, etc.). - Start from the rightmost column (ones place):
If the top digit is smaller than the bottom digit, you need to borrow. - Borrowing from a zero:
If you need to borrow from a zero in the next place value to the left, you’ll need to go further left until you find a digit you can borrow from.
When you find a digit to borrow from, reduce that digit by 1.
Change all the zeros in between to 9.
The zero you originally wanted to borrow from becomes 10. - Subtract:
Subtract the bottom digit from the top digit in each column, starting from the ones place.
Tips:
- Always start from the rightmost column.
- Be careful when borrowing across multiple zeros.
- Double-check your work to avoid mistakes.
