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.

What do you do with the decimal when adding?
When adding decimal numbers, the decimal points should be lined-up.
What is the rules adding decimal?
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.
What is Decimal Addition in math?
Decimal addition is adding numbers that are represented in decimal form.
When do you need to write zero as a placeholder when adding and subtracting decimals?
Adding decimal same as adding whole numbers
Why it is important to line up decimal numbers by their play value when you add or subtract them?
This is true for adding and subtracting ALL numbers, not just decimal representations.

Rules in adding or subtracting scientific notation?
- 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.

When do you need to write zero as a placeholder when adding and subtracting decimals?
Adding decimal same as adding whole numbers
How is adding decimals like adding whole numbers?
It can be same because it,s just the decimal
Why it is important to line up decimal numbers by their play value when you add or subtract them?
This is true for adding and subtracting ALL numbers, not just decimal representations.
When subtracting or adding numbers in scientific notation why do the exponents need to be the same?
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.
How is adding decimals similar to adding whole numbers?
Adding whole numbers is the addition of decimals where the decimal part is zero; in both cases the digits are place value aligned meaning that the decimal points, which lies between the units (or ones) and tenths columns, are aligned - in the whole number the decimal point is "hiding" at the end.
What is the difference between adding whole numbers and adding decimals?
The main difference is that with whole numbers the decimal point is "hiding" (after the last digit of each whole number) whereas with decimal numbers it is clearly visible. In both cases the numbers are added with the decimal points aligned - with whole numbers there are no digits after the decimal points so the decimal points are not written, but if they were they would be visible after the last digit of the whole numbers and they would be automatically aligned; with decimal numbers there may be a different number of digits after each decimal point so it is up to the person doing the arithmetic to ensure the decimal points are aligned.
Why is it important to align decimal point when adding or subtracting decimal numbers?
Because if you dont , your answer will be a whole number and that will make your answer wrong
Can all numbers be a decimal number?
Yes. Any integer can be transformed into a decimal number by adding a decimal point and then a zero after, for example: 3 = 3.0
