Lesson Fifteen: Decimal Review

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


              3.58		 4.33
            - 1.23             - 3.22
           --------           --------
              2.35               1.11


              4.48               4.55
            - 3.25             - 2.34
           --------           --------
              1.23               2.21
Just line up the decimal points and the columns will line up like they're supposed to. 

        3.33 - 2.22 = 1.11		4.44 - 3.22 = 1.22

        3.45 - 2.13 = 1.32		3.99 - 2.10 = 1.89
If you want you can re-write each of these problems vertically.

Now you get to try a few for yourself.
