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.
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
When adding decimal numbers, the decimal points should be lined-up.
Decimal addition is adding numbers that are represented in decimal form.
No, it makes no difference.
Ensure that the denominators are the same when adding or subtracting fractions.

When adding decimal numbers, the decimal points should be lined-up.
- when adding or subtracting in scientific notation, you must express the numbers as the same power of 10. This will often involve changing the decimal place of the coefficient.
line up the decimal point when your adding and subtracting. add annex a zero when you have extra number. sometimes you can use a number line.

You have to line up the decimal when adding but not when multiplying. Example: This one is adding 23.56+89.45 23.56 89.45 This one is multiplying 23.54*4.506 23.54 4.506
Adding decimal same as adding whole numbers
If there are any numbers which are integers and so do not have a decimal point, then append one at the extreme right. Then arrange all the numbers in a column, with their decimal points aligned. Ad up the numbers ignoring the decimal points entirely. In the answer insert a decimal point under the column of decimal points.
no
There is a system or strategy to adding them it is called DUD. Decimal Under Decimal 1.2 1.2+ 2.4 Now that's how you add decimals!!
