Subtracting decimals is similar to subtracting whole numbers. Add disks to model the minuend. In each place value column, remove disks from the minuend equal in number to the subtrahend. If there are not enough minuend disks to remove in a column, regroup from the columns to the left and continue. Write the total number of disks remaining in each place value.
