Arithmetic - Decimal Operations - 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. 


              .55		.83
            - .43             - .12
           -------           -------
              .12               .71


              .47               .69
            - .35             - .37
           -------           -------
              .12               .32
Once you line up the decimals, the rest is just subraction as usual. 

        .33 - .22 = .11		.45 - .22 = .23

        .45 - .13 = .32		.99 - .10 = .89
If you want you can re-write each of these problems vertically.

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


              3.48               4.55
            - 3.25             - 2.34
           --------           --------
              0.23               2.21
Just line up the decimal points and the columns will line up like they're supposed to. 

        3.33 - 3.22 = 0.11		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.
