?

Subtract column by column; start from the column on the right

Subtract the digits in the ones column:

1 - 8 = ?

The second digit is larger than the first.
Borrow from the next column to the left.

The borrowing is a two step process:


Subtract 1 from the top digit in the column of the tens: 7 - 1 = 6.
Cross out the top digit you've borrowed 1 from: 7.
Write the answer above that digit: 6.


When borrowing, 1 ten = 10 ones.
Add 10 to the top digit in the column of the ones: 10 + 1 = 11.

After borrowing, the subtraction has become:
11 - 8 = 10 + 1 - 8 = 10 + 1 - 8 = 1 + (10 - 8) = 1 + 2 = 3.
3 is the ones digit.
Write it down at the base of the ones column.
