Substraction

• Write the numbers one under the other, line up the decimal points.

• Add trailing zeros so the number have the same length

         $2$  $8$ $.$  $5$

      $-$ $0$  $9$ $.$  $5$

• Starting on the right and working left, subtract each column of numerals.

• Borrow a digit from the next column to the left if the digit being removed is greater than the digit above it.
• In the last Column subtract the second digit from the first : $5 - 5 = 0$

        $2$  $8$ $.$  $5$

     $-$ $0$  $9$ $.$  $5$

     $________$________

                  $0$
