Ad up the numbers ignoring the decimal points entirely. In the answer insert a decimal point under the column of decimal points.

Line up the decimal points in a vertical column. Then add the numbers while ignoring the decimal point. Finally, put a decimal point in the answer in the same column as for the summands.

Example of multiplying whole decimal numbers: 2.37 × 3.56 = 8.4372 Remove the decimal point and multiply as for whole numbers: 237 × 356 = 84372 Then add the decimal point, thus : 8.4372

Look at the digit after the decimal point. If it is bigger than 5, then add one to the last digit BEFORE the decimal point otherwise don't add. Then delete the decimal point and everything after it.

You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point. Thus (assuming the "short scale") you get: 53,620,000,000.You must add 9 digits (or 12 digits, depending on the country) after the decimal point, and eliminate the decimal point.
