Lesson Sixty-four: Decimal Subtraction

Lining up the decimals and subtracting just like you do with whole numbers is the best way to approach the subtraction of decimal values. 


              .551		 .832
            - .430             - .122
            -------            -------
              .121               .710


              .476               .693
            - .353             - .371
            -------            -------
              .123               .322
Once you line up the decimals, the rest is just subraction as usual. 

        .333 - .222 = .111		.452 - .221 = .231

        .454 - .131 = .323		.991 - .100 = .891
If you want you can re-write each of these problems vertically.

Now you get to try a few for yourself.
