Editing Addition (section)

==== Decimal fractions ====
[[Decimal fractions]] can be added by a simple modification of the above process.<ref>Rebecca Wingard-Nelson (2014) ''Decimals and Fractions: It's Easy'' Enslow Publishers, Inc.</ref> One aligns two decimal fractions above each other, with the decimal point in the same location. If necessary, one can add trailing zeros to a shorter decimal to make it the same length as the longer decimal. Finally, one performs the same addition process as above, except the decimal point is placed in the answer, exactly where it was placed in the summands.

As an example, 45.1 + 4.34 can be solved as follows:
    4 5 . 1 0
 +  0 4 . 3 4

    4 9 . 4 4
