addition of whole numbers. The difference is that there is a decimal point
to keep in mind. The decimals are put in a straight column; that is,

basically the same as they are in the subtraction of whole numbers.
Just as in the addition of decimals, the decimal points must be lined up

then the number on the bottom (subtrahend), then you must add zeros
