Lesson Sixty-four: Decimal Subtraction

Even when you have digits on both sides of the decimal point, subtracting is done as usual. 


              3.586		  4.331
            - 1.232             - 3.220
            --------            --------
              2.354               1.111


              4.487               4.556
            - 3.252             - 2.343
            --------            --------
              1.235               2.213
Just line up the decimal points and the columns will line up like they're supposed to. 

        3.335 - 2.223 = 1.112		4.448 - 3.221 = 1.227

        3.458 - 2.134 = 1.324		3.997 - 2.102 = 1.895
If you want you can re-write each of these problems vertically.

Now you get to try a few for yourself.
