Lesson One hundred and six: Adding Decimal Values

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


              3.51		 2.33
            + 4.23             + 3.22
           --------           --------
              7.74               5.55


              3.42               1.52
            + 3.25             + 2.34
           --------           --------
              6.67               3.86
Just line up the decimal points and the columns will line up like they're supposed to. 

        1.33 + 2.22 = 3.55		2.41 + 3.22 = 5.63

        2.45 + 2.13 = 4.58		1.09 + 2.10 = 3.19
If you want you can re-write each of these problems vertically.

Now you get to try a few for yourself.
